Yes, it should have been copy.  However, if you execute a program such
as the gdb from b19 that calls a cygwin build dll and it gets the one
with cygwin1.dll then you will crash with a core file as the two can't
exist in the process together.  You can check what dll's are getting
loaded with DJ's cygcheck program by `cygcheck programname.exe'.  If
you see both cygwin1.dll and cygwinb19.dll then you know that the
program will not run.

I posted yesterday an alternative to copying the dll for gdb.exe
subjected as "Windowed gdb?!?!"; so watch for it to find out what I did.
