Subject: Re: [AMBER] Compiling Amber with gfortran-4.5.0 on a mac

For your information, I observed the same problem with gfortran (gcc45
snapshot 20090924) until I got a new gfortran from gcc45 snapshot

I.e., this seems to be solved in a newer gfortran on Snow Leopard. My
guess it was a regression for some certain versions of the compiler.
