G++ Fundamental Types?

[Charles Jenkins]

I'm sorry to ask such a stupid question, but I am coming from a Borland C++ background, and although I have scoured http://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/, I cannot find a list of which fundamental built-in types GCC understands. I believe keywords like  __int8 and __int16 are Borland C++ extensions, and I'd like to know what equivalents I can use in GCC. Where can I find a list of all the basic, built-in types for C++? Thanks!
