I had completely forgotten about this bug report posted several days after I
first installed Linux on my computer :)

In the meantime:
* I switched to Linux near-full-time in 2006, for both home and work usage.
This computer cannot easily run VirtualBox VMs anymore. The simplest way to
perform native Windows builds and tests is now to use another computer from
work, which could take a bit of time, possibly not before the end of next week.

* I co-created the GCC4TI development environment out of the aforementioned
TIGCC. Among the various bugfixes and improvements we made, the following ones
are relevant to this discussion:
1) the custom build scripts do not delete ar, objcopy, objdump, size and strip
any longer (better having incomplete tools for expert usage than none at all
!);
2) GCC4TI's gcc and binutils use a program prefix, so that they don't collide
with system gcc and binutils;
3) the local patch to binutils was expanded one hack-ish hunk, so as to mask
out the offending flag and make the binutils more usable, though not
necessarily in the way upstream would do it. See the first hunk of 
https://github.com/debrouxl/gcc4ti/blob/4a0341f02f9d95a205b8601ca7be39cd876c5b1c/trunk/tigcc/gcc/gas-2.16-tigcc-patch.diff
.

* binutils, like many other programs, went through rounds of fuzzing and
subsequent bugfixing, while GCC's Windows support further improved.

The problem might therefore well be gone from modern binutils versions, only
testing will tell - but I can't do that today :)
