Certainly if you can stay within c++98 then you should. On a larger scale,
gcc42 support is optional, so c++03 is pretty close to being a safe ground.
Striving to support C++ by gcc3.x and gcc2.95 is worthless; but your C code
should benefit from being gcc2.95-compatible.
Of course, more different compilers help portability.
These are basic, obvious observations about how to develop good and friendly
code in FOSS world. I am honestly surprised when folks do not these things.
