^^^^^^^^^^^^^^
This is the one you want to change. The number is bytes*16 for its internal
heap. Try making it 2 or 3 times larger, try your program again, and repeat
as necessary.
But what version of CWSDPMI is this? You can type `cwsdpmi -v' to find out.
CWSDPMI versions beyond r2 have 6K by default, and this is only 2K. The
current version is r4. Consider upgrading.

Also make sure that there actually is 128M of free space on your c: drive.
Either this is a CWSDPMI peculiarity or you have only 4M of free space.
