No one has added support of XMM registers for DJGPP. One can see from 
gdb/go32-nat.c in gdb-6.6.tar.bz2.

I remember I had this problem already long time ago when building from 
sources and using RHIDE. I workarounded it in some way, but I don't 
remeber exactly how (perhaps limiting librhgdb not to try to retrieve 
XMM registers at all).
