Thanks for checking!

The patch that you found was first added in response to the mailing
list threads linked below, for the exact same reason that I tripped
over. Since then, another variant of the functions that were enclosed
in \r-eating loops was added and was not subsequently patched for
djgpp in the same way. For the sake of consistency, the nullptr checks
in all instances of the while loop should be made the same, though.

Apparently, the bash git repo is a huge mess. The DJGPP source zip(s)
need some getting used to, but at least a native build works somewhat
smoothly (the latest one required removing two instances of
SIGCHLD-blocking code lines). However, the djgpp zips seem to indicate
version 4.4.28 in the filename, but both the binary and the source
identify themselves as 4.4.23.

I have also been able to cross-compile it, which is quite tedious, as
you said, but the resulting binary does not work. It seems fine at
first, but once it is let loose on the first configure script, it will
break in weird ways ("cannot create temp file for here-document:
Permission denied (EACCES)".
