Yes, but very seldom. Anyways, the problem appears to be solved now.
I use an intermediate 16-bit program tu23.pas, written in Turbo Pascal:

tu22.c --spawnl--> tu23.pas --exec--> gcc

tu22.c is the new IDE program.
tu23.pas transmits the command line to exec,
and also holds a clock interrupt service routine,
which updates a "Line number" on the screen
while gcc is compiling. It works without errors,
well no errors yet in any case :).

(The TSR solution didn't work, the computer
locked up sometimes, so I had to reset it with
the reset button.)

Thanks for your help,
