Revision bc6b4f52fc79712db637ff90a472b82b32695e11 authored by Jason Riedy on 20 February 2007, 00:22:56 UTC, committed by Junio C Hamano on 20 February 2007, 02:20:30 UTC 
Add a compat/strtoumax.c for Solaris 8.
 
Solaris 8 was pre-c99, and they weren't willing to commit to
the strtoumax definition according to /usr/include/inttypes.h.

This adds NO_STRTOUMAX and NO_STRTOULL for ancient systems.
If NO_STRTOUMAX is defined, the routine in compat/strtoumax.c
will be used instead.  That routine passes its arguments to
strtoull unless NO_STRTOULL is defined.  If NO_STRTOULL, then
the routine uses strtoul (unsigned long).
