how to check that my programe respects the iso c++

[Matthieu Gallien]

Hello
I maintain an old software that was developped since twelve years.
I need to check for the best portability and the best maintainability.
The idea is to write cleanest c++. So I want to check for the respect of
the iso c++ of my code which originaly don't respect it. (It was first
compile with gcc2.7.x)
I made some modifications, but I am not sure to have terminate my job.
Sorry for my poor english

In g++, you can compile with the -std=c++98 flag set. This checks for
ISO-C++ ('98) conformance. However, I'm not sure if g++ itself is 100%
standard conformous. I think not. But it should do the job.

Twelve years is like ages for a C++ program

Get yourself a modern compiler like g++ 3.4. Compiler your code with the
appropriate compiler options (-W -Wall -ansi -pedantic ...) You may get
dozens of errors, if you have not been keeping up with the pace of changes
in C++ then get a good introductory level C++ also. Accelerated C++ (Koenig
& Moo) is a good option for that.
