Yes, the DJGPP port emulates X menus, see src/msdos.c.  (This
emulation could be the basis of similar support for text terminals on
Unix and GNU systems.)

Right.  It instead uses config.bat batch file and a bunch of Sed
scripts in the `msdos' subdirectory.

When Emacs 19.2x was ported to DJGPP, there was no Bash port yet, so
running a configure script was not an option.  An additional
disadvantage of using configure, even now, is that one needs lots of
ported packages to be installed, in addition to Bash.  By contrast,
config.bat uses only a small number of widely available ported
programs (Sed, mv, and rm, IIRC), and thus one can build Emacs with
only a minimal set of non-standard tools, which is good for a
fundamental tool such as Emacs, as it avoids a chicken-and-egg problem
to some extent.
