   Notes:
 
     [1] doesn't cope with makefiles with DOS line endings, so must mount
         emacs source with text!=binary.
     [2] fails when needs to invoke shell commands; okay invoking gcc etc.
-    [3] requires LC_MESSAGES support to build; maybe 2.95.x update to
-        cygwin provides this?
+    [3] requires LC_MESSAGES support to build; cannot build with early
+        versions of cygwin.
     [4] may fail on Windows 9X and Windows ME; if so, install Bash.
+    [5] fails when building leim due to the use of cygwin style paths.
+        May work if building emacs without leim.
