Thanks, this gets a little further now.

However, it seems to be that etags depends on gnulib regex now, and upon
enabling that module it complains about "langinfo.h" missing, which I
assume isn't in DJGPP.

I can't find any code to generate it in gnulib either.

So I'm confused: what did etags use in Emacs 26, when the MS-DOS build
still certainly worked?

Thanks.
