Thanks for this. The file go32stub.h is a "copy" of libc\stub\stub.h file
and it gets included in the libbfd.a library which is linked into these
exes. If anyone updates stub.h please remember that go32stub.h in the
Binutils may also need to be updated.

I diffed the 2.04 stub.h against the go32stub.h and there were allot more
changes then when I compared the 2.03 sub.h against the go32stub.h. The
changes in 2.03 v's go32stub.h are expected due to the date and time info in
the stub.

The stub.asm file changed in 2.04 and as such does this mean that so should
go32stub.h in Binutils when 2.04 is released?

The following is the change in the 2.04 stub.asm code:-

loadloop:
 mov ah, ';'   ; Copy until this character
 call store_env_string ; to "loadname"
 or al,al   ; Check terminating character                  << New Code
 jne @f1   ; If ';', continue                                      << New
Code
 dec di   ; else point at null for next pass.                << New Code
@f1:                                                                      <<
New Code
