Re: [liblo] windows weird...

It is strange, since a glance at the macros suggests that lo_htoo32()
should simply expand to htonl().  I'll try using gcc's -E flag to look
at post-preprocessor output and see if that's the case.

Either way I can't see how such a macro would lead to delays..
interesting.  Could be something a bit subtle.  Which VM are you
using, Parallels?
