[ECOS] Problem building binutils for SH-* under cygwin

["John M. Mills" <jmills at tga dot com>]

I want to build eCos-1.3.1 for the SH-3, and therefore need suitable
versions of binutils: eCos docs say that 2.9.1 is unsatisfactory. I don't
think my problem is SH-specific, but rather one between 'binutils' and
'cygwin'.

I can build 2.9.1 under Cygwin, but am not successful with
more recent snapshots nor releases. I fear the reason may be Cygwin's cpp
failing to parse a macro. My build log is:

****

**** and the line in question is:

#define	align_power(addr, align)	\
	( ((addr) + ((1<<(align))-1)) & (-1 << (align)))

****

Other failures follow and naturally the package won't build. Of course the
next thing I will need is the 'egcs' snapshot which is also recommended,
vs. gcc-2.95.2.

I checked the cross-gcc and binutils mail archives but didn't recognize my
problem there. I upgraded Cygwin, and am using 'make-3.77'. I ran
'dos2unix' on all the 'Makefile's, too, in case I had a problem arising
there.

Can anyone recommend a usable binutils which I can build for Cygwin-B20.1,
or suggest what is going wrong here?
