Is good to know that, but when I saw your problem I remmembered one I had. 
That's pretty strange, but if I compile large C++ code with tons of includes 
with low memory (let say 10Mb physical free and 128Mb swap free) I get internal 
errors, they dissapear when I make the same but with 19Mb of physical memory.
How can it be? DJGPP uses the disk to swap, what's the difference if the memory 
is from disk or from real memory? I think these are bugs in GCC. Any idea?
