Subject: configure: Don't put includes in function body of AC_LANG_PROGRAM

The second argument of AC_LANG_PROGRAM is the content of main function.
We cannot put any includes there, or we end up testing whether the
compiler supports nested functions because headers may have definitions
for inline functions.
