You said you did.  Look at the first quoted paragraph above.
You state you want to use the Linux synthetic target. That
means you need to cmpile for Linux.

For what target?  You need a Cygwin-hosted cross compiler for
the desired target.  Above you stated you wanted to build eCos
for the Linux synthetic target, so you need a Cygwin-hosted,
Linux-targetted cross compiler.

Because it appears you were using a Cygwin targetted compiler
(one that produces Win32 binaries instead of Linux ELF
binaries).  That won't work.

It's certainly a lot easier to build eCos under Linux, but you
don't have to.  You do have to compile it with an appropriate
cross-compiler.
