The files should all be identical for all platforms, apart from types
that are not universally available. The most common problem is that
Windows doesn't support long double, so the corbaidl_* files differ.
long long might be an issue on some platforms, too. If you don't need
to use such types, you can generate the headers for the most
restrictive platform you have, and they should work fine on other
platforms.

Cheers,

Duncan.
