Plenty of other people don't use gcc too, plenty of people have been
using the same platforms as you without issues.  The code you are
having problems has been tested over and over again on all the major
platforms over many years - the OSG hasn't just been ported to all its
platforms, and it hasn't just appeared overnight.  There is something
specific to the way you are building things that is breaking things.

using std::atof only works if you include cstdlib, so it'll break many
platforms.

We'll thats half the way there.  GLExtensions itself isn't a widely
included file so it doesn't pollute too much for the gain it provides.

We'd end up having to add losts of #ifdef using #endif blocks which is
really bad way to pollute the code.
