Also, there have been issues reported in the past where mass conversions like that hit some binary files in the source tree and caused the compile to fail and/or the resulting binary to not work properly. Restrict to *.c, *.h, and *.mak for safety.
Another reason why I prefer dos2unix. It is fairly accurate at ignoring anything that appears to be a non-text file.
Also, I'm looking about on software.opensuse.org, and while there are packages available, the releases are almost a year old year old (I don't know which one it is at the moment as I'm dualbooted into Windows at present)...
