 ITYM !=  With most C compilers either would
work. 
Really?  If so, it's an extension, since <> in that context is a syntax
error in C.  (Indeed, I can't think of any context in which it isn't a
syntax error in C, except cases like a string or character literal,
where almost any two source characters are acceptable, or cases like
part of a false #if block where it doesn't actually get compiled.)

Which compilers have you found accept it?
