Bootstrapping Emacs or recompiling Lisp files in the `lisp'
subdirectory using the various targets in the lisp/Makefile file
itself, you will only need that if you check-out development sources
from the Emacs source repository.
-Building the DJGPP version of Emacs is currently supported only on
-systems which support long file names (e.g. Windows 9X or Windows XP).
-You need to unpack Emacs distribution in a way that doesn't truncate
-the original long filenames to the DOS 8.3 namespace; the easiest way
-to do this is to use djtar program which comes with DJGPP, since it
-will behave consistently with the rest of DJGPP tools. Do _not_

On Windows NT and Windows 2000/XP/Vista/7, running "config msdos"
might print an error message like "VDM has been already loaded". This

synchronously, unlike on other platforms.
-Version 2.0 of djgpp has two bugs that affect Emacs. We've included
-corrected versions of two files from djgpp in the msdos subdirectory:
-is_exec.c and sigaction.c. To work around the bugs, compile these
-files and link them into temacs. Djgpp versions 2.01 and later have
-these bugs fixed, so upgrade if you can before building Emacs.
