Try -fpermissive .
I know a few people who have used -fpermissive to build stuff like gtk
  on solaris (which has many many lines of non-compliant code like the
  above in its old X11 headers) .

Of course, it is best to fix the code, since the C99 (new ANSI C
  standard) makes k & r style function defs errors.
