This is not the way to do it. Use AC_USE_SYSTEM_EXTENSIONS in autoconf, which detects libc settings.
The current autoconf shape is poor, long ago I offered James to rewrite it but he refused. I only made it partially work for cross compile. There are a lot of none standard/best practice stuff there. I did fix automake stuff... :) Alon.
