customize c++ syntax highlighting

[address@hidden]

Hi,

Just wondered if anyone could tell me how in C++ major mode I can make
emacs treat a specific word as being syntactically equivalent to a
default C++ type.

For example,

If I type "int foo();" "int" is coloured green and "foo" is coloured
blue, which is nice.

But if I type "mytype foo();" I don't get any colours at all. I'd like
mytype to be treated as if it were a default C++ type.

Thanks,

Sugi
