Issues with headers
===================
-There are various technical issues with the definitions contained in
-glibc's headers, listed below. The list below assumes GCC 3.3.2, 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
-be included in headers (if _XOPEN_SOURCE is defined appropriately)
-than ISO C permits.
+None known.
