If you are compiling on an MSDOG-like system which has long file

names, you may need to do `SET LFN=y' for some of the commands,

especially the compilation commands. It might be more convenient to

unpack the Emacs distribution with djtar, which comes with djgpp;
|

djtar truncates file names to 8.3 naming as it extracts files, even if
|
||||
the system allows long file names, and this ensures that build

procedures designed for 8.3 file names still work. Use as in `djtar x

foo.tar' or `djtar x foo.tgz'.

Some users report that running Emacs 19.29 requires dpmi memory

it. If we find out what change introduced this requirement, we will

try to eliminate it. It is possible that this problem happens only

improved dpmi handling means this is no longer a problem.)

You can find out if you have a dpmi host by running go32 (part of

djgpp) without arguments; it will tell you if it uses dpmi memory.
