First, you used the wrong list.  You seem to want to report a bug in
the compiler.  There is a list just for doing that that we created.
I'll copy the whole message there.

Second, you don't provide a complete testcase.  Certails the manual
and the webpages by now describe what a test case is.

I suspect the code in the headerfiles is not ANSI C code.  If that is
the case, we should probably fixincludes it.
