When running external programs such as a C compiler and getting an
error code, distutils only prints the program name.  With this change,
one can get the full command line by setting the DISTUTILS_DEBUG
environment variable.

This should have no compatibility issues, unless there are tools
that depend on the exact format of distutils debug messages.

This fifth tuple element is unsupported in an old hg version still used on
one buildbot, and it is not really necessary (only used in touch --help).

This was perhaps on the border between a bug fix and a feature since
the Python3 docs did not originally say it was unix only.  However, the
functions never worked anywhere but unix, and the docs were changed to
say it was unix only well before the windows support was added.

Unfortunately, windows support was added in 3.3.4 as well as 3.4.
That leaves us in the uncomfortable position of needing the tag to say
"version changed: 3.3.4" :(

pylauncher.vcxproj already has the same dependency, and adding it to
the pywlauncher project eliminates the possibility of the pywlauncher
build failing when building the solution in parallel.  In particular,
pywlauncher may fail to build when doing a "Rebuild Solution" from the
VS Build menu.
