PCH is IMO very valuable. GCC, ICC and MSVC support it, I'm not sure
about other compilers.
I've read your concerns, but I think they're not an issue.

It would be nice to add PCH support to the Hello World example. I
think this requires two steps:
1. Compile config.h into config.h.gch
2. Add config.h.gch as a dependency to all source files.

Could you (or someone else) help me with those? I've got no experience
with automake but I assume they're trivial for someone with
experience.
