A work-around is to set a user-defined symbol, say COMMON_PREPROCESSOR_DEFINITIONS to the definitions used everywhere, then put $(COMMON_PREPROCESSOR_DEFINITIONS) on the downstream definitions.

I don't have anything unusual.
In project setting, I put
GCC_PREPROCESSOR_DEFINITIONS = FOO
In target setting, I put
GCC_PREPROCESSOR_DEFINITIONS = $(inherited) BAR
And I got "FOO BAR"
It works too if I put some macros in an xcconfig file, and the uses $(inherited) at Project level.
