For people who use hardware most developers don't have access to, we
need preprocessed source and profiling data, or else there is no chance
of fixing it.  
It seems users of these platforms are not willing to provide this, even
when asked.  

Those people who have provided preprocessed source and profiling data
(8361, omniorb, etc) have had their compilation times sped up.
So whenever i hear that "we don't care about compilation time", i wonder
if the user has even put code in bugzilla that demonstrates the problem.
Most often, the answer is no, AFAICT.
