Big sigh.

The gnulib-related configure test checks for the declaration of
__fpending, but the build environment still tries to compile gnulib's
fpending.c.  But __fpending is defined as inline function in stdio_ext.h
so the definition in fpending.c clashes with the one in stdio_ext.h.

That's a bug in the gnulib build environment.  The definition of
__fpending should be skipped if HAVE_DECL___FPENDING is 1.

The problem is that this doesn't really help us a lot since all
packages with integrated gnulib are affected.

I'm not sure how to fix this yet.
