hi
why fbsd dont use precompiled headers during buildword/buildkernel? I just did
very naive test (which doesnt work for a lot of the headers)
cd /sys; find . -name \*.h -exec gcc -x c-header {} \;
time buildkernel
and delete those compiled headers and time buildkernel again
there is a speedup for the precompiled-headers case (but not very big) and I am sure if it
was carefully integrated into the build (ie. compiling all headers) the
difference might be quite visible...
thnx
roman
