This is somewhat in violation of the ANSI C rules about names. I have a patched version
of gcc 2.7.1 (vax vms) that translates ANSI C names (to those found in the DEC
runtime libraries) in the assembler, this is much like that done by DEC's DECC compiler.

I still have to fix the passing of some attributes via the name prefixing hack used by
gcc vax/vms.
