Does anyone understand what is going on here. I have a very complex
makefile for a very complex program. It gives the "undefine MAIN" error 
as above (not the others), but I have been able to link other complex 
situations. The solution of compiling all the *.f in one go is not really 
possible without a lot of work. The whole system and the makefiles are not
designed that way. So I am stuck unless I can understand this.

Regards, Brian.
