James,
If you want to build objcopy locally and have it linked against cygwin1.dll,
just compile it with Cygwin's compiler. Don't use the '-mno-cygwin'
flag. The 'binutils' package obviously builds 'objcopy' so you can consult
that package's process if you're having problems with building your custom
version.
