tony2001: ms libc putenv function does have at least one segfault bug
that we have a workaround for. Someone needs to check a debug build of
4.3 on windows; preferably someone with MS VC 6 installed, as the libc
has changed between releases. I'd check it myself, but I only have
vs.net installed, so it would be a bogus check.
