g++ default #include's

[Nafai]

Hello. I'm using a recent version of g++ compiler. It isn't necessary to
type some #include's with this compiler. But sometimes I have to use
older versions of g++ and I get a lot of errors because of not having
typed those #include's. Is there any option for g++ not to put
#include's itself?

Thanks.

That's not a C++ question, but a g++ question. Please ask
in the gnu groups. The FAQ can help you there.

HTH,

Look at your compiler documentation to see whether it defines its
version. Then you can do something like:

#ifdef GCC_VERSION < 0x1234566
#include <...>
#endif

I'm not sure what the define symbol is for gcc, but you should be able
to find out from the gcc folks.

Hope this helps,

Correction: Use '#if' instead of '#ifdef'.

More likely gnu.g++.help. Fairly low traffic though.
