I forgot to mention libsigc++ will drastically affect which compilers will
be able to compile LyX. It looks like gcc-2.7.2 will never work and
gcc-2.8.x is only just capable perhaps-maybe (sorry JMarc looks like
you'll have some extra work).
Libsigc++ is developed with egcs-1.1. It hasn't been tested with SUNs 5.0
compilers so that'll be an interesting challenge for Michael -- it should
work out of the box (just like LyX ;-) since SUNs compiler supports all
the right features.
There's a list of tested/supported compilers in the libsigc++ docs. I can
forward this to anyone who's too lazy to get a copy of libsigc++ for
themselves.
