Ah, good! If we care, it is easy enough to add a configure test to figure this kind of stuff out. Are you aware of any other Fortran compilers that don't accept -D, and if so, what flags they *do* accept? I would imagine a configure test that tries to compile a fortran program that requires some preprocessor symbol to be set and then tries a few different command line flags (e.g., -D, -WF,-D, ...etc.) to figure out which one works (if any). Hence, having a list of possible flags to check would be most useful. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
