3.2[.0] was supose to have just the C++ ABI change (as shown in
gcc/cp/ChangeLog), but it had a bit more in the base compiler.  Since
3.2[.0]'s release, a lot of changes have gone into gcc-3_2-branch.  Some
things that did not compile with 3.2.1, now compile due to fixes in the
gcc-3_2-branch.  But now other things that did compile cause ICE's.  It
has been a never ending chase since 2.95.3 to find a truly usable GCC.

cvs diff -u0 -r gcc_3_2_release -r gcc-3_2-branch, gcc/ChangeLog 508
lines of diff, and cp/ChangeLog has 63 lines of diff.  Bugs have been
added since 3.2.0.  FreeBSD is using a GCC 3.2.1 20020916 snapshot, and
it isn't anywhere near the quality what would have been 3.1.3 should be.
