4 ABI = Application Binary Interface. What vendors of debuggers and
5 other tools see when they work with the output of GCC. 3.2 is
6 compatible with version 3 of the spec.

14 Anything that compiled with 3.x will compile without change with
15 3.2. As stated, the only changes are to the ABI, what other tools
16 interface with.
18 Thus you would need the same changes to 2.95 code as you would for any
19 of the other 3.x compilers. My experience has been that bringing the
20 code into compliance with the ISO standards will fix any problems.
