You should apply these patches herein to the mit-root, before doing anything
other. Then call the script './SetupLinks' which will install all other
files, which are needed for building the release of X11R4. Note, if you are
using ESIX, you MUST also run SetupEsixLinks.

Check up mit/config/at386.cf before you start compiling.

If I didn't allready mention it, your original MIT-sources should have
patch-level 18.
