[Bug preprocessor/33473] New: GCC does not correctly generate dependencies correctly for precompiled headers

["rswan at signetic dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

Hello;

GCC does not correctly generate dependencies correctly with g++ -MD when
precompiled headers are used. I've attached an example which generates main.d
while compiling main.cpp. main.cpp includes include/bink.h. When the include
path contains the precompiled bink.h.gch (only), main.d does not contain any
dependency on bink.h.gch.

When the compiler includes bink.h, main.d includes the dependency.

I get the same behavior with version 3.4.6 and 4.1.2
