| 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. 

Perhaps.

| What I do not understand in the code you added for that, Lars, is that

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