When it saw the complete command line you gave it: cygpath -w "/usr/local/bin/tool -f /usr/src/source.c" It treated that string as a single filename that happened to include the subdirectory "/tool -f /" and properly converted the entire string to a single Windows path name. I think what you wanted to do was this: /usr/local/bin/tool -f `cygpath -w /usr/src/source.c` If you have a posix path, chances are, you're running bash or some script that understands them, so don't convert that. Else, do that conversion too.
