To the OP - Ian's right.
My question is what the preprocessor does here. Am fairly certain
that LINE is not a substitution for __LINE__ but rather the line
number in the header file where that directive was encountered -- is

OP - Is your question about __LINE__ or __FILE__? If there can be
such a thing as "MORE WRONG", then substituting FILE for __FILE__ is
much worse than LINE for __LINE__ (which as Ian pointed out is wrong).
