Good. Then lib/popen.c does not need to be extended. > > If yes, we'll also need an edit to doc/posix-functions/popen.texi. > > > > Part of 'Portability problems fixed by Gnulib:'? Yes.

I mean, in the third argument of AC_CACHE_CHECK, which is a set of shell statements, add the case "$host_os" in os2*) there, before the test program gets created. Similar to the first AC_CACHE_CHECK in m4/fenv-environment.m4. Bruno
