My main concern is with the register issue, since this is causing real
problems, so it would be great if someone else could comment on that.

Regarding the debug issue: turning debugging on or off doesn't matter in
this case. Here's the relevant code from src/lisp.h:

/*#ifdef DEBUG_XEMACS*/
#define REGISTER
#define register
/*#else*/
/*#define REGISTER register*/
/*#endif*/

All the ifdef's are commented out, so suggesting that debugging to be
turned off as a workaround here won't work. All of this is from the 21.4
code, BTW.

Kind regards,

Hans
