Declare cuserid in unistd.h for UNIX98 and before (bug 20043).
For UNIX98 and older X/Open standards, unistd.h should have a declaration of the legacy cuserid function, but such a declaration is missing. This patch adds that missing declaration. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20043] * posix/unistd.h [__USE_XOPEN && !__USE_XOPEN2K] (cuserid): New prototype.
