reserved identifier violation
I suggest to try the search pattern "_[A-Z]+" on the source files. You will find some places where names begin with an underscore and an uppercase letter.
This does not fit to the expected naming conventions of the C language standard. http://en.wikipedia.org/wiki/Reserved_identifier
