Yes - I have these in both.

I observe the following:

--> $prefix/bin/$target-ld -V
GNU ld version 2.16.91 20050610
  Supported emulations:
   aixrs6

--> $prefix/bin/$target-as --version

I see that the same original error message was seen by the author of this 
bug:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16627

Reading through the bug report it seems that he/she had an incorrect path. 
However, my path is:

/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/cygdrive/c/IBMDebug/bin:/cygdrive/c
/WINNT/system32:/cygdrive/c/WINNT:/cygdrive/c/WINNT/System32/Wbem:/cygdrive/c/PR
OGRA~1/IBM/CLIENT~1:/cygdrive/c/PROGRA~1/IBM/CLIENT~1/Shared:/cygdrive/c/PROGRA~
1/IBM/CLIENT~1/Emulator:/cygdrive/c/Program Files/Microsoft SQL 
Server/80/Tools/
Binn/:/cygdrive/c/php:/cygdrive/c/Program 
Files/vslick/win:/cygdrive/c/mysql/bin
:/usr/local/cross-tools/bin

so that when I type:

$ which as
/usr/local/bin/as
$ as --version
GNU assembler 2.16.91 20050610

When I installed cygwin, I simply got whatever gcc binaries came with it. 
Perhaps I should build gcc for host=target=i686-pc-cygwin before 
attempting to build the cross-compiler?

I notice this also:

$ uname -i
unknown
$ uname -p
unknown

Cygwin doesn't know what hardware platform or op sys I have (?!). Perhaps 
this confuses the configure script for gcc?

Any other thoughts on why this is not working?

Thanks!

(I should build this all on Linux - except for that means going through 
our IT guys to get permission for Linux box which they won't do until they 
can see the benefit - which is why I am attempting to demostrate cross 
compilation to them using cygwin!)
