(PR#6805) Re: [Rd] fix for a minor build error in R-1.9.0 with XFree86 4.4.0

[Prof Brian Ripley]

Thank you.  A better fix (one that does not change the behaviour on other
X11 installations) is already in the R-patched sources.  Would you please
check that works on your installation?

This is an error in the XFree86 4.4.0 headers, so please report it to 
them.
