I haven't tried it yet, but anecdotal advice from Andrew Tridgell indicates 
that Samba builds get a huge improvement. That is almost certainly helped by 
the particular Samba header file system, where they only ever include one 
header in each file (and it is always the same one - it includes everything 
else that is required), so they get a lot of assistance from pre-compiled 
headers.

Maybe we can get better performance by making a standard <kde-includes.h> that 
includes the 20 most common KDE headers and the 10 most common Qt headers. 
Then work through the KDE files and rip out the duplicates. Worth a try for 
someone with a lot of high performance hardware and a bit of spare time.
