don't know what it is.


Oh, that might just be me. But in your example above, gcc does not make
use of the precompiled headers.

Ah... Curious...


mkdir foo.h.gch
cc foo.h -o foo.h.gch/nopic
cc -fPIC foo.h -o foo.h.gch/pic

cc bar.c

? If you put the headers that you want to compile in include/, you can also avoid this problem I think.
