Subject: 2000-12-13  Jeff Johnston  <jjohnstn@redhat.com>

        * libc/stdlib/ldtoa.c (_ldcheck): New routine
        that categorizes a long double as NaN, Infinity, or other.
        * libc/stdio/vfprintf.c [WANT_IO_LONG_DBL](_VFPRINTF_R): Removed
        isinfl and isnanl static routines which were i386-specific.  Changed
        calls to the two removed routines to a single _ldcheck call.
        * libc/stdio/vfieeefp.h (ldieee): Fixed missing semi-colons.
