I should mention that libtool is clearly in the wrong with requesting
a test for "main" in the library since it is depending on a
side-effect and the technique is the result of sloth.  Autoconf is
also in the wrong since it didn't generate code which actually tests
for main in the library.  There are indeed libraries which may contain
a main routine (e.g. the Perl library) so it is valid to test for
'main' in a library.
