In IPC::Exe, I do the following:
# non-Unix: escape command so that it feels Unix-like
my @cmd = $non_unix
              ? map {
                    (my $x = $_)
                        =~ s/(\\"|")/$1 eq '"' ? '\\"' : '\\\\\\"'/ge;
                    qq("$x");
                } @_
              : @_;

before exec { $cmd[0] } @cmd; (See the quoting: test in t/02_IPC-Exe.t)

This helps to get around most of the quoting issues under Win32.
