23 rem YOU'LL NEED THE FOLLOWING UTILITIES TO MAKE EMACS:
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
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
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
38 rem mingw32/gcc-2.92.2 make (3.77): 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]
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?
