Hey,
   It's been seven months since I reported /beta/BNU217B.ZIP was too
big because it still had debug info and hadn't been stripped. And I've
been using the latest Binutils 2.17 on both XP and Vista with no
apparent problems. However, after Gordon (I think) updated the
package, he also UPX'd the binaries.
   Well, I've been using GCC 3.44 (and BNU2161B.ZIP) on my old P166
(DR-DOS only, heh) for quite a while, but I recently decided to
upgrade. And it didn't work, something was wrong (GPF whenever
running, trying to compile latest NASM). I finally found out that it
was Binutils causing the problem (e.g. AS.EXE, which is kinda
important). It may be a UPX bug (at the very least, UPX 3.02 won't
unpack it!!), but I dunno. All I know is that /beta/BNU217B.ZIP
doesn't work in pure DOS or DOSBox (although QEMU/FreeDOS and things
like XP or Vista work fine):  "invalid opcode" just for trying "as --
version" or "objdump --help". It was packed with UPX 3.01.
   The workaround is to just use /current/BNU217B.ZIP instead (which
uses the 2.04 stub unlike /beta/MAK381B.ZIP or /beta/DIF287B.ZIP or /
beta/PAT259B.ZIP, strangely). It was packed with UPX 2.93. I also
recompiled Binutils myself (.EXEs only, see link below for download
info).
