I recommend to avoid gcc versions prior to gcc-3.4. Over a decade ago I 
had to port code from gcc-3.2 to gcc-3.4
without losing support for gcc-3.2. Even though the code was much 
smaller than gdb it was a pain to support
both versions in parallel:
1. gcc-3.2 has an old C++ parser and supports a dialect of C++ which 
predates ISO C++.
2. gcc-3.2 does not have namespace
3. Requires STL as a separate library
4. Containers of the STL libraries do not understand allocators, and 
can't be taught to due to limitations in old C++
5. Templates have significantly different semantics, and define a 
one-pass parsing (unlike 2 pass in ISO C++).

Avoid gcc-3.2
