  Ah, there's your problem.  You typed a '1' instead of an 'l'.  And you
forgot the comma.

  No, wait a minute, I was wrong.  The actual problem is that you aren't
correctly describing what you've done.  Cut and paste stuff from your shell
into your email, don't just make it up or you'll inevitably get it wrong.

  Fortunately I can still tell what the actual error is:

  It's not a linker option in that sense; you just need to make sure you've
passed it to gcc or g++ along with all the .o files and it knows how to
drive the linker from that.  So just remove your -Wl altogether; the plain
old "-mno-cygwin" that you have immediately after the "g++" will do the job.
The effect it has is to cause g++.exe to pass different -L options to ld.


    cheers,
      DaveK
