I would benchmark that, at least in the old days the results of PCH where
really mixed:

http://wiki.openoffice.org/wiki/Build_Environment_Effort/Performance

and only reliably gave an advantage on incremental builds. OTOH, generating the
PCH for a library was a singlethreaded bottleneck in the old build system and
isnt anymore in gbuild, when doing a toplevel make, so this might be mitigated.

Anyway, worth a benchmark IMHO.

Best,
