[Swarm-Support] GCC numbering change

[Bill Northcott]

Just in case people are not regular visitors to the gcc web site, the 
steering committee has decided to rename gcc 3.5 as gcc 4.0.  This 
better reflects the major changes to the internals of the compiler.

So as to avoid confusion previous references to gcc-3.5 on these lists 
should be read as gcc-4.0.

Externally the compiler will not have changed that much except for the 
addition of Fortran 90/95 and a couple of extra libraries.

For MacOS hackers, Apple certainly intend to ship a compiler based on 
the new version with Tiger next year, but it is not clear whether it 
will be the default system compiler.  My suspicion is that it will be.

The Apple gcc-4.0 compilers can be built from CVS sources on the main 
GCC support sites. Fetch the code using  the tag apple-ppc-branch or 
better the latest in the Apple snapshot numbering series as of today, 
that is apple-gcc-1769. Such compilers can be used within the latest 
Panther/Xcode.
