So do "touch myfuncs.h" before the first file is built. Or invoke gcc -E in a
temp file for which you comment out the #include "myfuncs.h". Or make cproto do
any of this automatically.

Or even better, use libClang <http://clang.llvm.org/docs/Tooling.html> to do
what you want instead of parsing GCC errors, which are likely to change in
unexpected ways.
