[tex-live] xindy doesn't work on windows

In Unix shell, for example, in
export VAR="a b"
double quotes are removed and $VAR==a b, as it should be.
In cmd.exe, however, after
set VAR="a b"
echo %VAR%
gives
"a b"
This is one of peculiar features of cmd.exe.

I think xindy.pl can remove the double quotes in ENV's, if they
exist in MSWin case, before calling tmpnam().

Thanks,
Akira
