gcj does not build on Solaris (X11 headers incorrect)

[Martin Kahlert <martin dot kahlert at infineon dot com>]

Hi!
The current gcc version 3.0 20010221 (prerelease) does not
build on my Solaris 2.7 system with java support:

(about some hundred of these messages)


The problem are the headers of Sun's X11:
/usr/openwin/include/X11/Xlib.h:2063 looks like this:
extern XSetTransientForHint(
#if NeedFunctionPrototypes
    Display*            /* display */,
    Window              /* w */,
    Window              /* prop_window */
#endif
);

Neither 
extern int XSetTransientForHint 
nor 
extern void XSetTransientForHint.

The newly built g++ seems to insist on correct C++, but you will have to wait some
time for SUN to change their headers.

Any suggestions?

Bye,
Martin.
