GCC compiling nightmares

[Paine, Thomas Asa]

    I've been struggling to get some code to compile on different
versions of GCC.  The code uses STL, but it seems really impossible to
get it to compile on any newer installations of GCC.  The only
successfully building I have accomplished was on 2.96 (the box it was
developed on).  Newer 3.x stuff seems to have a really hard time with
it.  Are there any major drawbacks or pitfalls when working with newer
versions of GCC?  Guess I don't really know where to start looking for
compatibility issues.

Thanks,
