Hi,

(I know this isn't a serious issue, but I just wanted to clarify.)

(DJ said, "I bet it's L0<ctrl-A><something :-)", so he seems somewhat
familiar with the error.)

(Well, coincidentally ....)

Okay, so the problem is still there in latest BinUtils 2.27. This
hasn't worked correctly since 2.19 or such (yes, I re-tested).

The workaround is to use AT&T syntax. There is no problem when using that.

Confirmed with (Lucid/Ubuntu) Puppy Linux's 2.20.1, FPC/Win32's 2.22,
Cygwin's 2.25, and DJGPP's 2.27.

1). as newbefi.s -o newbefi.o

2a). (non-Windows only)
    ld -T ldscr.txt --oformat=binary newbefi.o -o newbefi.com
2b). (Windows only)
    ld -T ldscr.txt newbefi.o -o newbefi2.o
    objcopy -O binary newbefi2.o newbefi.com

So that was frustrating to deal with.    :-/
