comparison os2/dw.c @ 1781:a532ca0231ad
Attempt at fixing the issue noted in the last commit.
Seems the issue is stack related using VAC3.6...
We are supposed to allocate the stack in 4K blocks
on OS/2, so clamp the requested amount to a multiple
of 4K that is at least as big as the amount requested.
