i can't think of a compiler flag to get gcc to accept that, but i may yet be
of some help.

i assume you're running into this because you're including the same header
twice, right?  or a nice little recursive tree of dependant headers?  that's
when this usually pops up.  try something like this in your headers:

/* start of projectname header.h */
#ifndef __PROJECTNAME_HEADER_H__
#define __PROJECTNAME_HEADER_H__

/* contents of projectname header.h */

#endif /* __PROJECTNAME_HEADER_H__ */
/*end of pojectname header.h */

hope it helps,
chris
