Because it is better not to reinvent good code? I reused the configure code generated by AC_LINK_IFELSE: https://git.savannah.gnu.org/cgit/texinfo.git/commit/?id=6a3773cceec6c0858a176438c1bd6ac54a313e05 It should work well and be well integrated with the other checks, but it uses internal $ac_ext and ac_fn_c_try_link, so we'll have to make sure that it is still ok in the future, and probably reuse configure generated code if it changes to much. -- Pat
