Hi,

gcc201 is bigger than v1.39 and needs approximately 2Meg of memory.
when gcc calls the utility programs cpp, cc1, as, ld he frees memory
completely before loading them. So it might appear more disk
intensive. Try a good and large cache (2 - 3 meg).

The system call is made from the real mode. go32 saves its state, free
all the memory then issues the call. On return, the core of the
program is reloaded and 386 registers are reloaded from scratch. That
permits loading other protected mode programs like go32 itself with a
system call.
PS : go32 keeps approximately 112 k resident in memory when calling
system().

PS (concerning Alon Ziv message) :
concerning signal handling, they won't be available before sunday
night US central time. They will be in math.utexas.edu:/incoming. I
just finished the adaptation to the final release 1.06 of go32.

Regards.
