RTEMS Source Builder build error

[Joel Sherrill]

Is it a Cygwin version issue? Perhaps he has a different or older version

I have not seen this error. I have not been building in Cygwin for a
while because I could not get it to be stable enough to build all the tools.

As a test can you add '-nno-cygwin' to the optflags in
source-builder/sb/defaults.mc ? I have no idea what effects this will
have on the build.
