Thanks, I did that, and straightened out my use of these flags
somewhat, and now things seem to be working better.

My problem is getting everything working on an AIX. The fortran build
breaks there with a libtool problem.

I am getting make distcheck working in the hopes that by doing so, I
might in some way fix my libtool problems on AIX.

There were many subtle things wrong with my automake files that I have
corrected over the last two weeks, so this is not an entirely
unreasonable hope.

And now I can use make distcheck and it works, which is very
helpful. I will try on the AIX tomorrow and see how it fares.

Thanks!

Ed
