  23 rem   YOU'LL NEED THE FOLLOWING UTILITIES TO MAKE EMACS:
  24 rem
  25 rem   + MS Windows 95/98 or NT/2000
  26 rem   + either MSVC 2.x or later, or gcc-2.95 or later (with gmake 3.75
  27 rem     or later) and the Mingw32 and W32 API headers and libraries
  28 rem
  29 rem For reference, here is a list of which builds of gmake are known to
  30 rem work or not, and whether they work in the presence and/or absence of
  31 rem sh.exe.
  32 rem
  33 rem                                       sh exists     no sh
  34 rem  cygwin b20.1 make (3.75):            okay[1]       fails[2]
  35 rem  MSVC compiled gmake 3.77:            okay          okay
  36 rem  MSVC compiled gmake 3.78.1:          okay          okay
  37 rem  MSVC compiled gmake 3.79.1:          okay          okay

  39 rem  cygwin compiled gmake 3.77:          okay[1]       fails[2]
  40 rem  cygwin compiled gmake 3.78.1:        okay          fails[2]
  41 rem  cygwin compiled gmake 3.79.1:        couldn't build make[3]
  42 rem
  43 rem [1] doesn't cope with makefiles with DOS line endings, so must mount
  44 rem     emacs source with text!=binary.
  45 rem [2] fails when needs to invoke shell commands; okay invoking gcc etc.
  46 rem [3] requires LC_MESSAGES support to build; maybe 2.95.x update to
  47 rem     cygwin provides this?
