According to Andreas Schwab on 6/27/2008 7:06 AM:
| When AC_USE_SYSTEM_EXTENSIONS is expanded from a macro that also expands
| AC_PROG_CC for the first time then expansion order is wrong:
|
| $ cat configure.ac
| AC_INIT
| AC_DEFUN([FOO],[
| AC_PROG_CC
| AC_USE_SYSTEM_EXTENSIONS
| ])
| FOO
| AC_OUTPUT
I'm wondering if adding an AC_REQUIRE([AC_PROG_CC]) inside
AC_USE_SYSTEM_EXTENSIONS is sufficient, since it indeed attempts a compile
run. I'm experimenting with that idea now.
