If you have the memory, then setting EMXLOAD=X (x being the number of
minutes to keep the co,piler tools loaded) and GCCOPT=-pipe does speed up
compiling as cpp,cc1 and are started at the same time and output is passed
via a pipe. BTW, if you have 16 Mb or more and are using gmake, it pays to
call it with -jN, where N is the numbers of parallel tasks to start. But
this needs lots of memory, specially if you also use -pipe. On my 8 meg
system -j3 brought the system to crawl (three copies of cpp, cc1 and as in
memory at the same time.

BTW anybody know how to determine process load in OS/2 ? I ask, because GNU
make under unix uses system calls to determine the load and decide whether
to spawn new tasks or wait until the load gets lower. The current gmake
port I have just uses a dummy function that allways returns 'high load'. So
you have to manually give gmake a maximum jub number to use. Now if there
was a way to determine the load under OS/2 I could implement it in gmake.
