- Win32 modifications (thanks to Eric Lam for research and patches).
- Use MAXPATHLEN instead of PATH_MAX; add some casts (thanks to
bug report from Freddy Soderlund).
- Update exec documentation to clarify that it runs a single command
and closes the channel (thanks to Mike Schmidt).
- Use '' for tied PRINT output separator if undefined (stop warnings).
