There is also
    -imacros <file>
    Exactly like -include, except that any output produced by scanning
    file is thrown away. Macros it defines remain defined. This allows
    you to acquire all the macros from a header without also processing
    its declarations.

that may be useful if you run into other problems.
http://gcc.gnu.org/onlinedocs/gcc-4.2.1/gcc/Preprocessor-Options.html#Preprocessor-Options
lists other options that may be used for tricks in building.
