I don't have those. I hope they're not the problem.

That's odd.
I can compile the complete translation unit (single file):
-- contents of test_file.cpp --
typedef int FL_Button;
void OnBTNOKcallback(FL_Button *w, void *userdata);
-- end of test_file.cpp --
"g++ -c test_file.cpp" runs without error for me.
"g++ --version" reports:
g++ (GCC) 4.5.2 20101002 (prerelease) [svn/rev.164902 - mingw-w64/oz]
Maybe some of the other errors you report might be
the actual cause, but my test suggests that it's not
the compiler and not, in isolation, the specific line
of code you refer to.

Well, we're not using exactly the same version of the compiler,
but I really doubt it's the compiler. Can you compile my
test_file.cpp with your version of the compiler?
