[M3devel] put full paths to source files in debug info

[Jay]

ps: does anyone care that binaries built from different cvs checkouts, but otherwise identical source, will no longer match, unless perhaps they are "stripped"?
 
If so, or if any of the other issues bug people, or any other problem is brought up or discovered, this can be made a command line option. I will always turn it on. :)
