Using precompiled headers can hide missing include dependecies -
that's a fact and has already been discussed several times on this
list. Just because building with precompiled headers is *so much*
faster, most developers don't build without precompiled headers and
eventually submit changes which introduce dependencies which are not
reflected in the corresponding includeDB files and only compile by
chance (and precompiled headers:)
I would threfore strongly suggest to run a compilation *WITHOUT*
precompiled headers as preintegration test so prevent such problems in
PS: there still exist compilers which don't support precomiled headers...
