ta0kira, you're doing it wrong. Why should the compiler have to guess at the language of a header file, unless you're trying to compile that file directly (i.e. not via a #include in another file)? The included file is compiled in the same language as the including file. Therefore, it doesn't matter if I use .h as the extension or not, it only matters where I include it from.

You seem to be blaming gcc for doing what it's meant to.
