I don't think so; the first reason is that you have the problem for all
commands you use in backticks, be it cat or ls or a series of echoes (or at
least you should have the problem; I had to reinstall B20.1 for another
reason -- user compatibility for support :-) --  so I can't check right now,
but th eproper behavior is that all these write in text and as such they may
output CR/LFs).

The second reason is that cygwin *must* be UNIX compatible, so a cygwin-only
option to cat would be unusable for all people sharing shell scripts or
Makefiles between UNIX and cygwin ;-(

The third reason is that (as Chris already answered) you can use ash instead
of bash: ash *was* fixed in this respect and correctly strip CRs from the
output of backticks.

The last reason is that you can look at the source and submit a patch :-)
