This is a bug report for perl from [email protected],
generated with the help of perlbug 1.39 running under perl 5.12.0.


-----------------------------------------------------------------
[Please describe your issue here]


There is a problem with parsing command line arguments in Perl in windows:

for example this command in cmd.exe:

perl -E "say join qq(\n),@ARGV" "123 234\" 123

resulting:

123 234" 123

but it must be:

123 234\
123

Why it's important? Because filepath separator in windows is "\" and i can't
use long filepaths or UNC in arguments of scripts (for example "
\\server\share\some <file://server/share/some> folder\")

[Please do not change anything below this line]
