I think if you do anything, it should be to make Borland 100% compatable with
the Euphoria, like Watcom and GCC. The last time I tried Borland 5.5 with the
Euphoria to C translator v2.4 I had a hell of a time trying to get the
enviromental variables set, but once I did though, I did a test compile with
window.exw or winwire.exw (I forgot which); it translated/compiled, but when I
ran it, I got a machine exception. They both worked fine with OpenWatcom.

Perhaps it's better now with v2.5, I havent tried. But since then I've came to
the conclusion that 99 percent compatable just isnt good enough in some cases and
that only perfect is.

Maybe you can do some testing with it to see if you can reproduce the problem
with the 2.5 translator.
