The comments in m4/nocrash.m4 say it:

   ...This is useful to avoid triggering
   action from a background debugger and to avoid core dumps.

Hence "rm -f core" in a configure test would be wrong. Hmm, is gnulib is
the only package that has configure tests that may crash, or would it
be useful to move the 'nocrash' module to Autoconf (in the form of an
Autoconf built-in)?

Nearly perfect. Just this code here

             nocrash_init();

             int result = 0;

uses C99 features not in C89 (declaration after statement). Swap these, and
the patch is fine.
