Hi
I have been reading the documentation of GCC to see the caveats of
this compiler and I really wanted to start using GCC 4.0 because it
makes smaller code at faster compiling speeds. However, the docs
state that we SHOULD NOT use GCC 4.0 if we want to deploy on systems
earlier than Mac OS X 10.3.9. It is not said we CANNOT, only that we
SHOULDN'T. My question is: why shouldn't we? What's the penalty of
that? Will an app break because of that? Or we will find inexplicable
runtime errors?
Another question related to the first: is possible to compile my code
with GCC 4.0 to make sure that my code is cleaner and then shift back
to GCC 3.3 to assure compatibility with earlier Mac OS X versions, or
am I asking for trouble?
I would like to hear your thoughts on that.
TIA
