There is one problem with {$I %LINE%} and his friends, which restricts

get the line and file info for the place of the definition and not
for the place of the expansion.
I am playing around with the compiler for some weeks, maybe i will send
a patch ( in a couple of weeks, the code is somehow complicated ) if
desired.
But what is the cleaner way? To defer the expansion of {$I %xxx%}
inside macros, or to define c-like macros __LINE__ and __FILE__, maybe
with nicer names?
Defer expansion.
The use of {$I } is mandatory, since __LINE__ and friends are valid
pascal identifiers and this should not be changed by a macro.
