Re: [ECOS] Help creating synthetic targets on cygwin-pc.

I'm very much new to eCos... so I could be wrong...

Could it be something to do with the fact that you are not building it
for an i686-pc-linux-gnu host, but rather, a Cygwin host?  They are not
the same.

http://ecos.sourceware.org/docs-latest/ref/synth-porting.html seems to
suggest that this does not work on Windows... but I'd imagine you'd be
looking for a "cygwin" synthetic target, not an "i386linux" one.  Unless
of course you're trying to cross-compile the synthetic target from a
Win32 host, then the situation becomes very different indeed.
