It builds for RTEMS (sparc) with some new warnings:

I don't see any Cygwin ifdef's related to imag()
so I built for i386-rtems to see if it was related
to _LDBL_EQ_DBL. i386-rtems built with a few warnings.

We have an x86_64-rtems tool target in anticipation of
a port. I built a tool chain just to check this and
the newlib master built cleanly on that.

I am sorry but I am not duplicating this. What would
be different about Cygwin in this case?
