Thanks for the link, this will certainly help. As this goes into Module::Build territory, and I'm not keen on learning on how to make Module::Build add arbitrary commands to the created Build (well, Build.bat) script, I won't change my patch. Somebody with knowledge of Module::Build is welcome to take my patch and make things work right out of the box.

The appropriate commands would likely be (ignoring systems where we have command.com):

set SHELL=cmd.exe
[download]

... and, after appropriate munging in Perl to remove all offending directories in $ENV{PATH}:

set PATH=$cleaned_path
[download]

$cleaned_path would likely be something like:

my $cleaned_path = join ";",
                   grep { ! -f "$_\\sh.exe" && ! -f "$_\\cc1.exe" }
                   split /;/, $ENV{PATH}
                   ;
