Before you build, start a fresh shell and "echo $PATH".
type mips-rtems4.7-gcc.  Make sure they are what you think
they should be.

It is best to have a VERY clean environment when using Cygwin.
You need to get rid of the Windows parts of the PATH as well
as "." It is a security risk even if it isn't causing this.

Also do an "env" command and make sure LIB, CC, and anything
else that looks like it might be related to building software
relates to Cygwin not Windows.
