I'm guilty:

[andris AT ap bin]$ stubedit -v stubify.exe
-value-          -field description-
0x180000 (1536k) Minimum amount of stack space (bytes/K/M)
0x4000 (16k)     Size of real-memory transfer buffer (bytes/K/M)
""               Base name of file to actually run (max 8 chars, ""=self)
""               Value to pass as file component of argv[0] (max 16 chars, ""=default)
CWSDPMI.EXE      Program to load to provide DPMI services (if needed)


I had custom stubify.exe which set larger stack size.

I should update readme:DJGPP, as it contained wrong information.
