Actually, I used this in the early development stage.  It seems that
the default optimization option of MrC compiler is not compatible with
-DENABLE_CHECKING.  So those who want to use this should turn off the
optimization flags as I wrote in the patch for mac/inc/s-mac.h.

Thanks for the comments.  As far as I tested, GC_MAKE_GCPROS_NOOPS
seems to work well with the default optimization option.  But it
crashes at the startup if used with "-opt off" option above for
unknown reasons.
