Well, the above code runs /bin/tload, not your tload.  FWIW, /bin/tload is
a machine load visualizer from the procps package.

If you didn't forget to put double quotes around the invocation of
cygpath, your program should get the whole filename as one argument in
argv.  If even in that case your tload does not not like spaces in
filenames, that's probably a bug in your code.
