13 years agoftoastr, snprintf: ftoastr + snprintf module
Paul Eggert [Wed, 29 Dec 2010 09:25:46 +0000 (01:25 -0800)]
ftoastr, snprintf: ftoastr + snprintf module

* lib/ftoastr.c: Use GNULIB_SNPRINTF, not GNULIB_SNPRINTF_POSIX,
since the snprintf module now should be good enough here.
* modules/snprintf (configure.ac): Add gl_MODULE_INDICATOR([snprintf]).
It seems odd to have both gl_STDIO_MODULE_INDICATOR([snprintf])

GNULIB_SNPRINTF only for the test directory, and the latter
doesn't arrange for gl_STDIO_H_DEFAULTS to be called, so neither
seems to suffice by itself.

snprintf: port snprintf (NULL, 0, ...) to Solaris 8 and 9

This fixes a problem observed with the latest coreutils snapshot
that caused a test to fail on Solaris 8.  src/csplit.c's call
snprintf (NULL, 0, format, UINT_MAX) returns -1 on Solaris 9 and
earlier, instead of returning the number of bytes that would have
been generated; this causes csplit to incorrectly report memory
exhaustion.
