As noted in this thread:
http://gcc.gnu.org/ml/gcc/2005-01/msg01087.html
there is no way to make use of a precompiled header without
-I- in a VPATH build in case the header source and the C or
C++ source file including it reside in the same source directory.
Please consider adding a flag (-icwd?) to the preprocessor which will
cause the current directory to be search for pch before the source
directory. Or consider to change the default pch search order.
