Thanks.  I've installed the patch.

As I mentioned in a previous message, if the if-else warning is giving
false positives, then that's a bug and we should put a test in the testsuite
for it -- not leave in non-conforming code in the g77 backend.

Additionally, most (all?) of the changes I saw in this patch fixed
the exact kind of problem that that warning was supposed to catch ie

	if
	 if
	 else

Now, the C language says exactly how this is supposed to be parsed,  so
it is not ambigious, but it *is* poor practice to write such code and
is a violation of the GNU coding standards.  I believe this is the case
that the if-else warning is supposed to be catching...
