Hi,


In A Research Project We Are Using Already Preprocessed C Code, Where We
Have To Map Source Code Positions Back Onto The Original Sources. Until
Gcc-3 Came Out, We Have Used The Gcc Preprocessor And Reconstructed The
Column Position From The Preprocessed Code. This only works as long as
there was no macro in that line. Now in gcc-3, the preprocessor doesn't
preserve whitespace any longer and we have to use a different
preprocessor. This raised the question, if there is a c preprocessor
that not only annotates the preprocessed code with line number
information but also includes column information?


Regards,
Ben
