I suspect that the problem is with the GnuWin32 port, rather than with 
netpbm itself.  I'll raise a bug report on the GnuWin32 list, (although 
Kees may see it here anyway).

I'd already anticipated this request; I've committed this:

2007-09-10  Keith Marshall  <address@hidden>

        * README.MinGW: Add warnings about use of MSYS-RXVT, and about
        defective GnuWin32 versions of netpbm/libpng.
