Problems building RTEMS for M68k in CYGWIN environment

[Joel Sherrill]

Cygwin sometimes inherits environment variables from Windows that are 
specific
to Visual Studio and confuse GCC.  Do a "env" command and look for variables
like CC, LIBS, etc that are set.

But you need to also make sure you can compile and run a native hello world.
That's what appears to have failed.  Look in config.log for details.

I'm having problems with the actual building of RTEMS (Chapter 5). Specifically the problem appears to be when I attempt to configure the environment. The configure command I'm executing looks like the following:
