  I'm not sure it's about Windows, as much as it's about cmd.com /
command.com.  I've never tried setting $ENV{PERL5SHELL} to specify bash,
even when I had bash for Windows, so I'm guessing ...

  That at least is documented:

perlfunc:
  On Windows, only the "system PROGRAM LIST" syntax will reliably avoid
using the shell; "system LIST", even with more than one element, will fall
back to the shell if the first spawn fails.

perlport:
  (Win32) "system LIST" without the use of indirect object syntax ("system
PROGRAM LIST") may fall back to trying the shell if the first "spawn()"
fails.
