Problems building RTEMS for M68k in CYGWIN environment

[Sreejith kurup]

Try making the folder \tmp\rtemsdocs-4.6.5 in the folder b-gcc or the folder
containing b-gcc.

Watch out for definitions for the Microchip tools as well.  I got badly
burned with very strange make errors that took a couple of days to isolate
to the definitions set up for Microchip tools.

I believe you'll find them if you search for anything with MCC in your
environment variables.

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.

trying to get past the learning curve. At this point I'm just trying to
install rtems 4.6.5 for a m68k target (actually its a M68377, CPU32 based)
and a gen68340 BSP. The host I'm using is a Windows XP machine running
CYGWIN.

with RTEMS" documentation and all has went as planned until now. 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:
