Well, I slipped my estimation, by at least two days :) I rebased my work on
OpenBSD version of the Sun's files. They looked easier to port, better
organized,
and they have arm headers written for it. Next I've ported the
newlib/libm/math/
testsuite the mingw32ce, which triggered a few bugs and missings in mingw32ce,
and I'm currently looking through the failures.
I should have learned by now to never promise dates... blah on me.
Cheers,
Pedro Alves
