There is also
-imacros <file>
Exactly like -include, except that any output produced by scanning

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.
