rem   YOU'LL NEED THE FOLLOWING UTILITIES TO MAKE EMACS:\r
rem\r
rem   + MS Windows 95/98 or NT/2000\r
rem   + either MSVC 2.x or later, or gcc-2.95 or later (with gmake 3.75\r
rem     or later) and the Mingw32 and W32 API headers and libraries\r
rem\r
rem For reference, here is a list of which builds of gmake are known to\r
rem work or not, and whether they work in the presence and/or absence of\r
rem sh.exe.\r

rem [2] fails when needs to invoke shell commands; okay invoking gcc etc.\r
