Really?

At least I built gdb-20000327 for DJGPP without problems (thanks Eli 
for that) but as I tested problem seems to still be there:
	I cannot inspect floating pount values in function which return 
	double in register (p ..., shows something like X.XXXXXe-312)

I used gcc-2.95.2 (my last not released build about 2 weeks ago).
Tried   "-g"and "-gstabs+3": no difference.

Also. Had to hack RHIDE rather much to be able to build it using this
snapshot. After that it seems to work Ok, but the nuisance with 
displaying double values is still not gone of course.
