The DJGPP port of GCC 2.95.3 does produce the code I described.
Perhaps on GNU/Linux, the library and/or the kernel somehow do the
equivalent of it, I don't know enough about GCC configuration on that
platform to tell.

I'll try if no one else does.

I tried that on fencepost (they also have GCC 2.95.4 there), and it
didn't open-code sqrt under -O0.
