Subject: Use gnulib's vsnprintf module.
X-Git-Tag: v1.3~166
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/bd7cc50d498bc0dcf403af437accdc82dea5f587

Use gnulib's vsnprintf module.

The snprintf module provides only snprintf, not vsnprintf.  As we
currently depend on both functions in the library, it is necessary
to use both modules.

This fixes failures in the new cdeclerr test on HP-UX 11, which has
vsnprintf but it is not entirely C99-like (wrong return value).
