Win32 update

Win32 update

The win32 make fails because it cannot find "camel.ico".

Even if I add a camel.ico stolen from elsewhere, the build
fails due to lack of "resource.h" referenced in "perl.rc"
(when using VC++ 2.0).

The following patch simply disables binding the icon resource
into perl.exe.  (One can always associate a bare *.ico file
to any executable, so it's not like it *has* to be bound
into perl.exe when building it.)
