What I told them, but they don't really seem to get it...
Anyway I'll probably drop gcc2 support for NetSurf, the only real
use-case for that is a replicant on the desktop, but the code isn't
working correctly yet (crashes on removal).
Though it'd be cool to demo... but they keep adding C99 things and don't
want to support C89 and keep reminding me of that (while they have no
problem supporting RISC-OS which is way older than BeOS :-P)
BeHappy can be compiled with gcc4 and use NS as a gcc4 replicant anyway.
Hopefully that'll keep them happy and allow me to push for other ugly
things instead :D
François.
