Given the data below, is the Cygwin port of ld expected to support "binary" and/or "ihex" ld OUTPUT_FORMATS().  As an aside, a native Red Hat Linux host was used to test the same inputs, the results were as one would expect, i.e. a raw binary format in x.out and an Intel HEX Format in x.out respectively.  Furthermore, searches in FAQs did not yield such an observation nor did searching the documentation set an expectation of not being supported.  Of course, I could have overlooked something,
