I thought a bit about that recently, and I don't like the idea of having to
support parts of another vendor's extension. The first other idea I had was to
add that STDCALL specification as an extension to the BIND syntax:
BIND(C,STDCALL). It is the logical place to put it, but it has to be protected
by macros to compile on other compilers, which is not very Fortran-ish.
So, my next idea is to provide an compile-time option that would make all
BIND(C) procedures in the compiled file STDCALL: true, this does not solve the
problem of existing code, and true, it requires creating different source files
if you want to use mixed calling conventions, but it seems like an good
alternative to satisfy our Windows power users and yet not add too much extra
kludge to the front-end.
