I mean GCC from gcc-4_0-branch in GCC's CVS.

As far as the sparc is concerned, no, it should work "out-of-the-box".
For some other targets (avr, i386), patches are required, the c4x
doesn't build.

Also you will want to use newlib from newlib CVS-trunk in newlib's CVS.
For the sparc it should work "out-of-the-box", some other targets
require further patches (avr, c4x).
