I assume you really meant C:\WINDOWS\TEMP here (as without the first slash it probably wouldn't work). Anyways, it depends on the app how it handles temporary files. Usually they seem to check TMPDIR, TEMP, TMP, /tmp, or similar.

Okay, but unless you have DJGPP=c:\djgpp\djgpp.env set or TMPDIR manually set to it, that won't affect anything.
Anyways, that wasn't the problem, so no worries.

There are too many GCC versions over the years, so the Emacs dudes don't test all of them. Last I read somewhere, they only tested certain 4.x versions. Unfortunately, DJGPP's unexec() apparently relies on COFF debug info, which is horribly deprecated and somewhat broken in newer releases.
Somewhat blindly guessing, it's probably best to try GCC 3.4.4 (like Eli does) or 4.4.5 or older. Though a few years ago I tried 2.95.3 on Emacs 23.1, and that didn't work, so that's probably too old. (Silly but unfortunate problem.)

In theory, everything would work fine, but reality is different. Anyways, 20.5 is much older, so I guess it didn't stress test GCC as much.

Latest BinUtils for DJGPP is 2.22r3 (though the Zip Picker still suggest that older one, for now). However, I don't think it matters here (and you don't need NASM at all).

For GNU Emacs, you need Make, GCC, BinUtils, DJDEV, mv, rm, sed. I think that's all. I can't remember needing much else. mv and rm are in DJGPP's FileUtils (fil41b.zip).
I don't recall compiling MicroEmacs '06 (JASSPA, presumably) nor SetEDIT (needs C++, right?). I did a few times recompile Quake, but it's a little bitrotted for DOS (they didn't re-test in 1999 source release), esp. due to *nix sbrk() handling, so you have to set a crt0 flag somewhere (and it won't run on NT-based machines due to near ptrs).

org-mode sounds too complicated for me, but I've not looked too closely.

Okay, though I know nil about that. :-P

Recompiling is easier, but I (weakly) tried to also make a binary patch. Dunno if hexl mode and -batch would allow for a potential to patch itself, heh.

The only unofficial DJGPP build I'm aware of is below (but I've never tried it nor GnuPG in general):

Be sure to post back whether any of this helps!
