Yes - this is what Rainer Schnitker does in his wdk tools.

It may be easier - but it's gross.  He has a program which
writes the glue functions using tons of asm statements to push
the arguments.

I'd argue that it's cleaner to get GCC to do this properly
on your behalf, rather than including yet another level
of indirection and crap.

Fraid so.  (eg, wsprintf)

I don't know, I never got down to that level - since I wanted to link
in with the windows library.

My meta-goal is to write a windows front end for GDB.  I thought that
cross compiling on my sun for a dos target using go32 technology would
help me; I could use unix build tools, long filenames, make, symbolic
links etc etc.

I've put this on hold now, and I run the code I'm developing on the Sun
and have the GUI on windows (in VC++) talking to it with winsock.  One day
I'll have to bite the bullet - either compile GDB with VC++ or get
go32 talking to windows.
