#1026 CPP -C Double Spaces Multi-line /* comments */

[David Mace]

I've been using cpp for some non-C related things, and discovered this one.

gcc-core-3.4.2-20040916-1.tar.gz

If you invoke CPP separately, instructing it to retain the comments (-C), and the file has DOS (\r\n) encoded newlines, multi-line comments get double-spaced.

/**
* I span a three lines
**/

Come out like this...

/**

* I span a three lines

**/

When carriage returns are stripped, cpp -C myfile.c doesn't double-space comments.

This buggers the line count for external tools as a side-effect.
