gnulib provides an implementation of frexp, however I'm wondering whether gnulib's implementation can be considered sub-optimal, as it has to be generic, compared to the internal Win32 implementation, which can use assembly. I truly don't know, I never tried to compare performance.
I checked in the following change: http://hg.savannah.gnu.org/hgweb/octave/rev/573f865aa8c8 If someone shows that the gnulib function is slow or doesn't solve the problem that we have, then I think we should try to improve the gnulib function. jwe
