This is why calling conventions, data type layouts, and object file
formats (including limitations on external symbol names) are best
specified by OS vendors, or even by separate standards organizations
(e.g. COFF), rather than by compiler implementors.  After a program is
compiled, it shouldn't matter what language it was written in, what
compiler was used to compile it, etc.
