rem [3] requires LC_MESSAGES support to build; cannot build with early\r
rem     versions of cygwin.\r
rem [4] may fail on Windows 9X and Windows ME; if so, install Bash.\r
rem [5] fails when building leim due to the use of cygwin style paths.\r
rem     May work if building emacs without leim.\r
rem [6] need to uncomment 3 lines in nt/gmake.defs that invoke `cygpath';\r
