Lars in your case.
The configure script does not fail if there is no prototype in
headers. I have found an autoconf macro which is as follows:
AC_DEFUN([AC_FUNC_SNPRINTF],
[AC_CACHE_CHECK(for working snprintf, ac_cv_func_snprintf,
[AC_TRY_RUN([#include stdio.h
int main () { exit (!(3 = snprintf(NULL,0,"%d",100))); }
], ac_cv_func_snprintf=yes, ac_cv_func_snprintf=no,
ac_cv_func_snprintf=no)])
if test $ac_cv_func_snprintf = yes; then
AC_DEFINE(HAVE_SNPRINTF)
fi
])
We could maybe just take this one or one which just does the link
part.
Lars Perhaps some thing changes in the environment inside/outside
Lars configure...
What I do not understand in the code you added for that, Lars, is that
snprintf.o is always linked in. Am I wrong assuming that we never use
the system-provided version?

I belive we use the system provided one if it exists.
