It requires so much change that I have made fairly quickly a functioning implementation and put it on a compiler explorer here: http://column.gcc-future.tk/# I've also managed to make source_location return a "better value", the only issue being that the newly created __builtin_COLUMN function returns the location of the opening parenthesis of the function call instead of the beginning of the function name.

Either way tracking the column number would require signif= icant changes to GCC that they haven't been willing to do so far even t= hough they have source_location implemented (currently returning 0).

That definitely settles this for me. I feel no= need to push this idea further.
