I honestly don't know which is why I suggested he setup a test to try it.

I do know that at the lower structural levels, there is some compatibility
between the native VMS tools and the binutils versions I tried and there's
clearly been some effort to make libbfd and some of the tools built around
it compatible with the VMS tools.

For example, I found that the same file formats were used for the VMS
Alpha binutils librarian and the native VMS librarian (although there
are some VMS Alpha specific bugs in the FSF version of binutils.)

I have no idea however how much the compatibility extends to the code
and standards layered on top of these structures when it comes to
multi-language/multi-compiler support and debugging programs.

Simon.
