Actually, the gnulib 'extensions' module already ensures that
_POSIX_PTHREAD_SEMANTICS gets defined (and likewise _XOPEN_SOURCE on HP-UX).

This patch updates the doc accordingly.


2010-04-25  Bruno Haible  <address@hidden>

        Use the 'extensions' module for some more functions on Solaris.
        * doc/posix-functions/asctime_r.texi: Recommend to use the 'extensions'
        module.
        * doc/posix-functions/ctime_r.texi: Likewise.
        * doc/posix-functions/getgrgid_r.texi: Likewise.
        * doc/posix-functions/getgrnam_r.texi: Likewise.
        * doc/posix-functions/getpwnam_r.texi: Likewise.
        * doc/posix-functions/getpwuid_r.texi: Likewise.
        * doc/posix-functions/readdir_r.texi: Likewise.
        * doc/posix-functions/sigwait.texi: Likewise.
        * m4/getlogin_r.m4 (gl_FUNC_GETLOGIN_R): Add comment.
        * doc/posix-functions/getlogin_r.texi: Mark Solaris problem as fixed.
