This is a modified version of Ghostscript, patched as below.
The changes are:
 - Change error code with mswinpr2 printing cancelled, to
   make exit a little cleaner.
 - Remove mswinrp2 temporary file when printing cancelled.
 - Fix TextAlphaBits=4 bug, which resulted in xscale=4, yscale=1
   instead of the correct xscale=2, yscale=2.
 - Fix arcto bug.
 - Return error code for 'gs -h', to force Win32 GUI Ghostscript 
   to pause on exit.

The original Ghostscript distribution is in
  ftp://ftp.cs.wisc.edu/ghost/aladdin/gs401w32.zip.orig
