If you don't want to be bothered with installing/learning D, I can send you the executable?

Send it over would be great !! (I'll /msg you the address.)
Having another tool that outputs this info would be handy. I'm currently using a "print_binary" function from tests/tmpfr_set_ld.c (in the mpfr source) but it purports to show me the actual value I pass it, not the correct value ... and it's starting to look like the 2 can differ.

At some point I might like to give D a try. I see that there's a GCC variant (gcd), but I gather that it's the one provided by Digital Mars (dmd, version 2) that would normally be recommended ?

Cheers,
Rob
