I keep finding mixed opinions as to whether or not calling into MFC from 
MingW should or shouldn't work.  The MingW project shows msvcrt capability 
to exist which I thought would spoof or at least borrow on the MFC libs 
themselves, but then it seems to choke when running into MFC, so I can tell 
if the support is or isn't functional.

I adopted a little project that was written in VS C++ 06 and I have only 04 
rev. libs on board for one thing.  I was hoping to keep the original project 
in it's basic native form and write "around" the differences, if practical. 
So far I have 14 errors and many are dependency issues, as stupid as 
glorified printf's, but in this case it looks to be coming down to socket 
threading issues which are not necessarily trivial to just "write around".

Yeah.  It looks like hacking it up may be more trouble than it's worth, 
where if I could have created a maintainable crossover, the project would 
make sense to take on, where a re-write would be a little too much for the 
value of the effort.

I would prefer to move away from M$ dependency and continue to look for 
cross platform ways of dealing with Windows applications.  I really don't 
want to pay to upgrade old MFC libs for one little project, nor do I want to 
stay in VS C++.  Express 2005 conversion to C++ would have been nice but of 
course Bill broke that off in our tailpipes by excluding MFC and other 
critical support unless you purchase the 2005 pro version of C++.

I don't mind writing in C# 05 Express from scratch, when someone needs it 
but otherwise I continue to work toward MingW and keep most of my efforts 
closer to Linux based life, onboard the Win box as most of what I produce 
for my own purposes will be .Net Mono/standard M$.  I'm having pretty good 
luck maintaining cross portability with some fairly substantial apps this 
way.

Thanks for your words.
