I installed cygport and built vim using Adam's command.  It wanted
some libraries that I don't have installed, such as for X, which
I don't use on Windows, so I modified vim.cygport to not require
those.  The result ran a little slower than /usr/bin/vim.  So to
really understand this, I will probably have to install those
libraries and run vim.cygport unmodified.

However, by changing CFLAGS to remove -g3 and add -O2 for my own
build, and by stripping the binary, the startup time for vim to edit
a particular file dropped from 8 seconds to 2 seconds, and even
using /usr/bin/vim takes 1.4 seconds, so I'm happy for now.

Thanks, Adam, for the help.

Regards,
Gary
