Subject: 2001-01-29  Jeff Johnston  <jjohnstn@redhat.com>

        * libc/include/math.h (signgam): Change to errno-like solution
        using a function to return the address of the real signgam.
        * libc/reent/signgam.c: New file containing __signgam().
        * libc/reent/Makefile.am: Added signgam.c to list of files.
        * libc/reent/Makefile.in: Regenerated.
