Define __CORRECT_ISO_CPP_STRING_H_PROTO correctly for Clang.
In the string/string.h and string/strings.h headers, we have a couple
of macros that "tell the caller that we provide correct C++
prototypes" according to the comment; they are used to determine
whether to wrap some prototypes in "extern "C++"" (and provide
multiple overloads of them, and some other magic) when __cplusplus is
defined.
The macros are set to check for sufficiently-recent GCC versions (4.4
and later), but this is not the right check for non-GCC compilers. In
particular, these macros should also be set when using Clang -- if
they are not set, then Clang will be unable to correctly diagnose a
number of subtle bugs that will be errors in GCC compilations.
As per discussion on earlier versions of this patch, rather than
restrict the fix to Clang per se, we assume that all C++ compilers that
claim to fully support C++98 are using a standard-conforming C++
standard library, which seems pretty reasonable. Clang has been
providing an appropriate value of __cplusplus since May 2012.

Fix ldbl-128 lgammal for small negative arguments (bug 16337).
This patch fixes bug 16337, ldbl-128 lgammal spurious overflows for
small negative arguments (the arguments in question are already in the
testsuite). The implementation uses the reflection formula to compute
lgamma of negative x from lgamma of -x, effectively resulting in a
calculation -log(x^2) + log(-x); cancellation isn't problematic in
this case (bugs for problematic cancellation in lgamma are 2542, 2543,
2558), but the x^2 calculation can underflow (in which case there is
spurious logic to return an overflowing value - lgamma can only ever
correctly overflow for large positive arguments, though tgamma can
overflow for small arguments of either sign as well as large positive
arguments). The fix is simply to calculate the result directly with
logl when the argument is a small enough negative number.
Tested mips64.

Fix x86 / x86_64 expl / expl10l wild results in directed rounding modes (bug 16356).
This patch fixes bug 16356, bad results from x86 / x86_64 expl /
exp10l in directed rounding modes, the most serious of the bugs shown
up by my patch expanding libm test coverage. When I fixed bug 16293,
I thought it was only necessary to set round-to-nearest when using
frndint in expm1 functions, because in other cases the cancellation
error from having the resulting fractional part close to 1 or -1 would
not be significant. However, in expl and exp10l, the way the final
fractional part gets computed (something more complicated than a
simple subtraction, because more precision is needed than you'd get
that way) can result in a value outside the range [-1, 1] when the
argument to frndint was very close to an integer and was rounded the
"wrong" way because of the rounding mode - and the f2xm1 instruction
has undefined results if its argument is outside [-1, 1], so resulting
in the large errors seen. So this patch removes the USE_AS_EXPM1L
conditionals on the round-to-nearest settings, so all of expl, expm1l
and exp10l now get round-to-nearest used for frndint (meaning the
final fractional part can at most be slightly above 0.5 in
magnitude). Associated tests of exp and exp10 are added and testing
of exp10 in directed rounding modes enabled.

Don't make soft-fp symbols compat symbols for powerpc-nofpu.
sysdeps/powerpc/powerpc32/libgcc-compat.S makes certain symbols that
glibc once accidentally reexported from libgcc into compat symbols.
Where the exports were purely accidental, this is the right thing to
do. However, for powerpc-nofpu the soft-fp symbols are deliberately
exported from libc, given public versions in
sysdeps/powerpc/nofpu/Versions and used by libm in preference to the
libgcc versions that do not support the software exceptions and
rounding modes. The libc versions should also be usable by user
programs, though normally libgcc gets linked in first (meaning,
effectively, that the <fenv.h> functions are broken as regards their
expected effects on user arithmetic).
A longstanding todo item is to remove the functions in question from
libgcc (when built with recent enough glibc) - that is, remove them
from static libgcc and make them compat symbols in shared libgcc - so
that this works properly (this is one of the items mentioned at
<http://gcc.gnu.org/wiki/Software_floating_point> - parts of that page
are obviously out of date, but this item still applies). Doing this
requires first that the functions are actually available from libc for
new links, not just as compat symbols.
This patch stops the symbols in question being compat symbols for
powerpc-nofpu. The nofpu Versions entries for them are removed (the
symbols never were exported at GLIBC_2.3.2, only GLIBC_2.0, because
the compat symbols took precedence).
Tested powerpc-nofpu. The symbols are no longer compat symbols and
libm.so now properly gets undefined references to them (resolved to
libc.so) instead of the libgcc copies getting linked into libm as
before.

Disable libm-test test name beautification for M_* constants.
math/gen-libm-test.pl has code to beautify names of various constants,

This has become decreasingly relevant over time for the M_* constants,

Fix x86/x86_64 expm1 inaccuracy near 0 in directed rounding modes (bug 16293).
Bug 16293 is inaccuracy of x86/x86_64 versions of expm1, near 0 in
directed rounding modes, that arises from frndint rounding the
exponent to 1 or -1 instead of 0, resulting in large cancellation
error. This inaccuracy in turn affects other functions such as sinh
that use expm1. This patch fixes the problem by setting
round-to-nearest mode temporarily around the affected calls to
frndint. I don't think this is needed for other uses of frndint, such
as in exp itself, as only for expm1 is the cancellation error
significant.

Add _DEFAULT_SOURCE feature test macro.
This patch adds a feature test macro _DEFAULT_SOURCE to enable the
default set of header declarations.
The intention is: if _DEFAULT_SOURCE is not used there is no change to
the set of __USE_* macros glibc defines; if it's used on its own, and
without compiler options such as -std=c99 that define __STRICT_ANSI__,
again, there is no change; if it's used together with the macros it
approximately (i.e., apart from __USE_POSIX_IMPLICITLY) implies
(-D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809L), again, there
is no change. Otherwise, it causes the relevant features to be
enabled, even if __STRICT_ANSI__, or another feature test macro, would
cause them to be disabled.
This macro deliberately bundles the POSIX.1-2008 (non-X/Open)
functionality with the BSD/SVID/"misc" functionality, rather than
defining a macro that gives just the latter, as many of the header
cleanups resulting from removing _BSD_SOURCE and _SVID_SOURCE support
are only possible when BSD/SVID/"misc" is always bundled with
POSIX.1-2008.
