* Replace Gcc test from top level configure.in with one from

util/configure.in.

* Modify top level configure.in and util/makeshlib.sh so AIX can
build/use shared libs with Gcc.

+	* configure.in: For paranoid GPL reasons, don't take the Gcc test
+        directly from the autoconf sources.  Instead, borrow my paraphrase
+        of this test from util/configure.in.  It's slightly cleaner
+        anyway.  Also, adjust AIX shared libs to work with Gcc.

 	* aclocal.m4 (_MAKE_SUBDIRS): Fixed so that error propogates
 		upward if -[ik] not specified.
