If you ask whether the ABI will be unchanged between 3.2, 3.2.1,
and 3.2.2, the answer is Yes.

3.2.1 for sure, 3.2.2 possibly (probably depending on the actual release
dates of 3.2.1 and 3.3.)

It's my understanding that 3.3 will be ABI-compatible with 3.2 either a)
out of the box, or b) by provding a flag which requests this compliance.

We are, unfortunately, aware of several problems in GCC 3.2 which already
have been fixed on mainline (which will become GCC 3.3). These fixed are
keyed to an internal flag, but as far as I know it has not yet been
decided what the default setting of that flag will be in GCC 3.3.

This I'll shortly adress both issues by updating that page. 3.2.1 has
not been released yet.

If you have any further questions (or updates/patches for the web page),
please do not hesitate!
