Mark, it seems you forgot to include the patch to tm-i386.h as per the
above ChageLog entry.

Thanks!  This solves the original problem I reported for the DJGPP port, 
for -gstabs and -gcoff compilation.  (We are discussing the best way to 
handle DWARF2 on the DJGPP developers' list.)

This also solved a year-old bug report whereby "print d", where `d' was a 
double stored in a register, would print garbage (we know now that this 
was because GDB was using a wrong register).
