m4-1.4.7 on DEC Alpha OSF/1 with alternate snprintf() library

[Nelson H. F. Beebe]

As I reported recently, the problem with the snprintf() library built
from

        http://www.ijs.si/software/snprintf/snprintf_2.2.tar.gz

on DEC Alpha OSF/1 4.0 that caused a test failure with m4-1.4.7 goes
away when that library is omitted from LIBS at configure time.

Since then, we have tracked down another, more complete,
implementation of snprintf() in the GPL code at

        http://www.netsw.org/system/libs/string/snprintfv-0.98h.tar.gz

I've just built a library with it using the native cc compiler,
-lsnprintfv, and rerun the test builds of m4-1.4.7 with cc and gcc
using that library.  All tests pass flawlessly.

Thus, the snprintfv library seems to be an acceptable fallback for
those older systems that lack snprintf() in -lc, and I plan to replace
-lsnprintf and -lgccsnprintf with -lsnprintfv in builds on OSF/1 4.0.

In the list of almost 30 systems for which I posted m4-1.4.7 build
successes yesterday, OSF/1 4.0 is the ONLY once that lacks snprintf(),
which is part of both POSIX and C99 (but absent from C89).  Even
Minix-3 and the NetBSD and OpenBSD SIMH VAXes have snprintf().
