GNU CPP reports the column number, not the char index, AFAICT. Try the attached file.

CPP returns the following error for the attached file:

ctest22.c:3:13: macro "undefined" requires 2 arguments, but only 1 given undefined;

13 is exactly the index of the closing paren. In the same time, with tab size 4, the 13-nth column is at the character 'd' from "undefined".

I am using CPP version 3.4.4

$ cpp --version cpp (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Copyright (C) 2004 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Interesting - this behaviour changed around GCC 3.4 it seems. One other small piece of evidence is that Emacs' C-x = command returns a column number, not a char index. Ok, given that most of the world seems to want char indices (or doesn't care), I'm happy for GHC to report char indices. Cheers, Simon
