clarification: is this a suggestion of a way to fix the problem myself
(so I can call programs), or a suggestion to the developers?

in 4.0.6, popen() would just call CreateProcess() with the specified
command.
this was ok.
in 4.1.0 popen() now prepends "cmd.exe /c " (or "command.com /c " on
win9x).
the problem with this, is that many web admins will disable access for
the web apps to access cmd.exe (eg, MS's IISLockDown does this), and
hence even though the web app may have access to c:\utils\myapp.exe, a
command like exec("c:\utils\myapp.exe") now fails on 4.1.0 but works on
on 4.0.6.
also, the hardcoding of cmd.exe should not be done. it should get it
from the enviroment.
summary:
have commands that prepend the result of an enviroment lookup on
"%comspec% /c " to the front of a command
AND
have commands that dont, so that I can call exec("c:\utils\myapp.exe");
without having to enable access to cmd.exe
OR
any interpretation of these issues, that allow for a sensible amount of
flexibilty.
