Adding the /useenv means that one's PATH actually gets through. This is

important for the _ssl.vproj build. It calls build_ssl.py which tries to
find a Perl to use. Without "/useenv" Visual Studio is getting a PATH
from somewhere else (presumably from its internal environment
configuration). The result is that build_ssl.py fallsback to its
"well-known" locations for a Perl install.
