See regformats directory!
reg-m68k.dat define 31
fpcode and fpflags are not known to linux, but I don't know
for other targets...
Maybe we should add a new packet that would
give out the name and the format of all the registers that are sent
in the register packet.
This would be sent by the remote GDB program at
connexion and gdbserver would then
and use the result of that first packet
to check which register he connected GDB wants,
if we know them and if the format is correct.
