Daniel,
Thanks for your commit, I was working on a 6.5 version, so far from the 
HEAD.
About the warning, gcc4.1.1 emit the following:
    remote-utils.c:653: warning: value computed is not used
I think it is because the returned value of strncpy is not used but it 
seems to be a gcc4.1 problem. Moreover it occures only in -01 or -02.

About your patch, the infinite loop has gone but I'm having a 
segmentation fault when argument are reversed.
I'm about to propose a patch in a new mail to avoid confusion.
