   #ifndef XGCTYPE
   /* The distinction does not exist now that the MARKBIT has been eliminated.  
*/
   #define XGCTYPE(a) XTYPE (a)
   #endif

The GC_foo macros shouldn't matter any more.  I haven't removed them yet,
because when I installed my "remove markbits" patch I wanted to keep changes
to a minimum to ease acceptance, debugging, and maintenance, and afterwards
it seemed too close to the release.

PS: But of course the make_fixnum_or_float call was problematic, so this
remark doesn't make any difference w.r.t the patch that Kim installed.
