Sort of. Its a bug which appears with recent cygwin packages. See

http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000095

You can get an updated version of configtool from 

http://www.ecoscentric.com/devzone/configtool.shtml

ecos.db in the packages target. arm7tdmi is a processor not a
target. eCos targets are real boards, not processors, since a target
is much more than just the processor.

You need to compare your hardware with the other ARM targets and
decide which is the closet. You then need to use that as a starting
point for your port. There is information about porting eCos in

http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html

And the book "Embedded Software Development with eCos"
