_________________________________________________________________
+3.5 _XOPEN_SOURCE / _GNU_SOURCE / etc is always defined
+
+ On Solaris, g++ (but not gcc) always defines the preprocessor macro
+ _XOPEN_SOURCE. On GNU/Linux, the same happens with _GNU_SOURCE. (This
+ is not an exhaustive list; other macros and other platforms are also
+ affected.)
+
+ These macros are typically used in C library headers, guarding new
+ versions of functions from their older versions. The C++ standard
+ library includes the C standard library, but it requires the C90
+ version, which for backwards-compatability reasons is often not the
+ default for many vendors.
+
+ More to the point, the C++ standard requires behavior which is only
+ available on certain platforms after certain symbols are defined.
+ Usually the issue involves I/O-related typedefs. In order to ensure
+ correctness, the compiler simply predefines those symbols.
+
+ Note that it's not enough to #define them only when the library is
+ being built (during installation). Since we don't have an 'export'
+ keyword, much of the library exists as headers, which means that the
+ symbols must also be defined as your programs are parsed and compiled.
+
+ To see which symbols are defined, look for CPLUSPLUS_CPP_SPEC in the
+ gcc config headers for your target (and try changing them to see what
+ happens when building complicated code). You can also run "g++ -E -dM
+ - < /dev/null" to display a list of predefined macros for any
+ particular installation.
+
+ This has been discussed on the mailing lists [67]quite a bit.
+
+ This method is something of a wart. We'd like to find a cleaner
+ solution, but nobody yet has contributed the time.
