Ack! Port from Borland C++ 5.01A to B20.1 buggy!

Hi all. I'm working on porting a game I've been writing from Borland C++
5.01A to cygwin B20.1. I've gotten around windowsx.h macros not existing,
and problems with having to link to cygwin1.dll (-mno-cygwin now used).
Now the program runs. It is a board game with a lot of BitBlt()ing and
StretchBlt()ing.
The problem is that my program will often crash just after processing a
WM_TIMER or a WM_PAINT message. Occasionally it will crash in WM_PAINT
after a BitBlt() to the screen's device context. This will occur after,
perhaps, 30 seconds, or 100 moves.
If the same code is compiled using Borland C++, the problem does not
occur. Is this just a really subtle bug on my part, or is it possible
this is a compiler bug?
I'll run some more tests while waiting for replies.
Mark
