/* For DOS, the libc exception handler routine must be free to call its
   own setjmp/longjmp functions--which use a different format buffer from
   ours.  Thus, we must not replace the existing setjmp/longjmp functions.

   We kludge our way around this by using macros to redefine the function
   names.  This is a potential sore spot if linked with binaries that do
   not include pthread.h! 

   These macros are also defined in src/dos/setjmp.S. */
