That's strange :( What arguments are it sent to the function? Since this
is an API function, it really shouldn't behave differently between mingw
and msvc, so it must be something that goes wrong with the arguments.

Also, Tom mentioned earlier that we may be including *two* replacements
for unsetenv(), which could be what's causing the problem. Can you check
if that is happening and try to disable the one in port/unsetenv.c and
see if that changes things?
