Hi. I adopted the bc package about a year ago, since fish uses it and I maintain
fish for Cygwin.

I think L.A. is right that because this is an issue of integration between
Cygwin and cmd, it's in the category of a nice-to-have feature. But I get that
it would be useful for you, and maybe for others too.

I haven't looked at the bc source code. It could take some time to find where
the issue is.  A place to start would be to compare the code archives:

http://ftp.gnu.org/gnu/bc/bc-1.06.tar.gz
http://alpha.gnu.org/gnu/bc/bc-1.06.95.tar.bz2

If you were to localize the problem in the source code and even propose a patch,
that would make it a lot more likely to get the problem fixed. Heck, you might
even get a gold star. I maintain the gold star page too :)

Andrew
