Re: [Libreoffice] Mac OS 10.4 Support

actually I'm compiling with SDK 10.5 and gcc 4.2.1 right now and it is
picking up quite few more WaE.
so gcc-4.0 is not over-picky, quite the contrary... and that is
probably why we get away with -Werror on Mac.

Also 10.4 + gcc 4.0 means 32 bits only... I'm finding issue with 64
bits support and deprecated stuff in Cairo for instance( like
something similar to
http://lists.cairographics.org/archives/cairo-bugs/2009-February/002951.html
)
none of these are that hard to fix... but they take time... time that
will be in even more short supply if we wait until we are _forced_
suddenly have to support a new SDKs (whether that means 2 build or
not). so the sooner we iron these quirk the better.

Ok so what if I made the default to 10.4 in configure.in so that one
can only build against another SDK if he explicitly ask for it ?

The problem right now is that you CANNOT use any other SDK since 10.4
is hard-coded
so 'new feature' are out of question, two codpath/fallback or not.
