You're correct about Perl, my bad.  My path in my CMD was pointing to Windows Perl.
Windows Perl does not strip out the backslash. Cygwin Perl is stripping out the backslash.

$ cat a.pl
$pcount = 0;
while ( $pcount <= ($#ARGV )) {
    printf("%s\n",$ARGV[$pcount]);
    $pcount ++;
}

$ perl a.pl -s "dsfgdsfgfsg d\:\\hello"
-s
dsfgdsfgfsg d\:\hello

K:\> c:\cygwin\bin\perl a.pl -s "dsfgdsfgfsg d\:\\hello"
-s
dsfgdsfgfsg d\:\hello

So if I compile with MS Visual Studio, binaries do not strip backslashes out of
arguments whether run in bash or cmd.  

If I compile with Cygwin gcc, backslashes are stripped whether in bash or cmd.

This looks like a compiler issue to me unless someone knows of an option.
