It kicks the snot out of GCC for SPARC code generation. I did give you a copy. In case it isn't obvious, using this makefile with a different compiler (called suncc for instance) is done by: $ make GCC=suncc vax Let me know how things work out.... You'll also have to change any GCC-specific options ("-f<xxx") in the Makefile. I don't think gcc specific options are used if the compiler isn't gcc. That is why I'd like to know 'how things work out'.... I seem to recall that they were, the last time I did it, but it has been awhile since I did that build. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
