not sure if this still applies correctly anymore, but
here's what i had (tested with gcc -H to make sure it
was using the pch..)

that very well may be true about the certain versions
of gcc or maybe gnustep only includes what is
necessary in each file and it takes longer to read the
large pch file than to compile the necesary headers 

just speculation I really don't know.
