    Is there a good reason that the font identifier in the font structure
    returned from
	fontp = XQueryFont(dpy,XDefaultGC(dpy,scn))->gid) ;
    is not a valid font id?

It's the same old (tired) argument about resource id allocation being
a client responsibility, there's no a priori id to assign to it, it
would require special mechanism (deemed unnecessary) to assign an id
to it.

    In addition, attempting to extract the font identifier for a default gc
    returns a 0xffffffff

If you are reaching into a gc, you are writing non-portable code.  The
gc structure in Xlib is supposed to be opaque, there is absolutely no
guarantee about how it's implemented.

    which sometimes is accepted as a valid font identifier and sometimes
    is rejected

If it succeeds, its probably a server bug.
