  50 rem [1] doesn't cope with makefiles with DOS line endings, so must mount
  51 rem     emacs source with text!=binary.
  52 rem [2] fails when needs to invoke shell commands; okay invoking gcc etc.
  53 rem [3] requires LC_MESSAGES support to build; cannot build with early
  54 rem     versions of cygwin.
  55 rem [4] may fail on Windows 9X and Windows ME; if so, install Bash.
  56 rem [5] fails when building leim due to the use of cygwin style paths.
  57 rem     May work if building emacs without leim.
  58 rem [6] need to uncomment 3 lines in nt/gmake.defs that invoke `cygpath';
  59 rem     look for "cygpath" near line 85 of gmake.defs.
