+Conformance of the GNU libc with various standards
+==================================================
+
+The GNU libc is designed to be conformant with existing standard as
+far as possible. TO ensure this I've run various tests. The results
+are presented here.
+
+
+Open Group's hdrchk
+-------------------
+
+The hdrchk test suite is available from the Open Group at
+
+ ftp://ftp.rdg.opengroup.org/pub/unsupported/stdtools/hdrchk/
+
+I've last run the suite on 1998-07-08 on a Linux/ix86 system with the
+following results [*]:
+
+ FIPS No reported problems
+
+ POSIX90 No reported problems
+
+ XPG3 No reported problems
+
+ XPG4 The wide character I/O stuff is missing in glibc.

+Missing: extern wint_t ungetwc();
+Missing: extern size_t wcsftime();
+*** Completed wchar.h
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ Beside this a problem in stdio.h is reported but
+ this is only because the scripts don't understand
+ the sometimes complex constructs in the header.
+
+ POSIX96 Same as UNIX98 [see below].
+ UNIX98 Quite a lot of problems, almost all due to limitations
+ of the Linux kernel (2.1.108):

+Missing: extern wchar_t *wcswcs();
+Missing: extern int wprintf();
+Missing: extern int wscanf();
+*** Completed wchar.h
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ Only the `wchar.h' problems result from glibc
+ defficiencies since we still don't support wide
+ character I/O.
+
+[*] Since the scripts are not clever enough for the way gcc handles
+include files (namely, putting some of them in gcc-local directory) I
+copied over the iso646.h, float.h, and stddef.h headers and ignored the
+problems resulting from the splitted limits.h file).
