Defects in the C99 standard
===========================
-The definition of macros such as INT8_C in <stdint.h> and <inttypes.h>
-is not implementable (Defect Report #209); this is expected to be
-fixed in a Technical Corrigendum to make the macros yield a constant
-expression of the promoted type (for example, int rather than char)
-rather than needing to be able to represent constants of type char.
-glibc follows this corrected version.
-
-Several of the <fenv.h> functions are specified to return void, but
-Defect Report #202 points out that under some circumstances they may
-need to return an error status. They are expected to be corrected to
-return int; glibc follows this corrected specification.
+Some defects in C99 were corrected in Technical Corrigendum 1 to that
+standard. glibc follows the corrected specification.
Implementation of library functions
For most of the headers required of freestanding implementations,
glibc relies on GCC to provide correct versions. (At present, glibc
-provides <stdint.h>, and GCC doesn't.) GCC's <float.h> is missing
-FLT_EVAL_METHOD and DECIMAL_DIG.
+provides <stdint.h>, and GCC doesn't.)
Implementing MATH_ERRNO, MATH_ERREXCEPT and math_errhandling in
<math.h> needs compiler support: see

There are various technical issues with the definitions contained in
-glibc's headers, listed below. The list below assumes current CVS GCC
-as of 2001-01-10, and relates to i686-linux; older GCC may lead to
-more problems in the headers.

Note that the _t suffix is reserved by POSIX, but not by pure ISO C.
Also, the Single Unix Specification generally requires more types to
