Re: 3.0 20010305 (prerelease) gen-num-limits.cc compile failure o n alpha-dec-osf4.0e

I've diffed the V4.0E and V4.0F versions of <standards.h>: the affected
area of the header is unchanged between those releases (as well as between
V4.0G and V5.1).  During my bootstraps of 3.0 20010221, that header was
fixincluded as follows:

--- /usr/include/standards.h	Fri Aug 25 06:20:14 2000
+++ ../gcc-3.0-20010221/gcc/include/standards.h.fixincl	Wed Feb 21 23:34:17 2001

 #endif

and g++ defines __STDC__ as 1, but not __STRICT_ANSI__, so just disabling
this fix gives the right result for both C and C++.

That's what I had done manually at first (while keeping the conversion to
__STRICT_ANSI__ instead of __STDC__), but just undoing the fix proved to be
simpler, and just as effective.
