Actually, gnuclient has clean_string which appears to quote things correctly, so I don't need to convert \ to /. Darryl> [ Also, I think much of your patch was correct.

The only clearly broken part was translating the drive Darryl> letters (e.g., "c:\" to "/c/"). ] Here is an updated that uses your suggested solution. It appears to work. Should that be conditionalized on just __CYGWIN32__ or should it be defined(__CYGWIN32__) && !defined(WINDOWSNT)? This patch still doesn't handle the case of "\foo". If someone can tell me how to get the current drive letter, I'll fix this too. Ray
