Peter,
I once tried to write code that would issue no warnings, and ended
up going in circles -- changes that eliminated warnings on one
platform would generate them on another. Sounds impossible, but a good
example is one compiler knows that an exception or longjump jumps out
of a function, so a following return stmt is unreachable code, whereas
another compiler will know nothing about the exception and complain
that you aren't returning a value. Anyway, I agree we should try to
turn off warnings that are not warning us about real bugs. The trick
is to be cross-platform and not turn off the possibility of getting
new useful warnings in the future. If anyone knows the best way to do
this or even a solid "best practices" approach, please let me know.
Hi Roger,
I would put the #pragma inside an #if defined(_MSC_VER)
You can check for the _MSC_VER if you just want to use those pragma for
a specific version of VC.
Here is an example:
#if defined(_MSC_VER)
#pragma warning( disable : 4290 ) // we don't care about exception
specification ignored
#endif
