[PATCH] fix for Darwin shared library support

From: Joe Orton
Subject: [PATCH] fix for Darwin shared library support
Date: Tue, 28 Oct 2003 16:57:38 +0000
User-agent: Mutt/1.4.1i

Christian Schaffner tracked down a bug where libtool HEAD fails
to detect shared library support in the linker on Darwin.

This occurs in a configure script using AC_LIBTOOL_TAGS([]), because
AC_LIBTOOL_PROG_LD_SHLIBS is using $GXX not $GCC, but $GXX is not set.
The fix Christian wrote is below.  

Is there an alternative to using AC_LIBTOOL_TAGS([]) - without this I
can't seem to produce a configure script which works on a system without
a C++ compiler?
