bc version has issue with \r when run from cmd

[dapiot holmp]

the version of bc that comes with cygwin, is bc 1.06.95   it works
fine from within the cygwin environment, but from cmd it doesn't
process \r

C:\cygwin\bin>echo 5+4|.\bc
(standard_in) 1: illegal character: ^M

C:\cygwin\bin>

C:\cygwin\bin>echo 5+4|tr -d '\r'|.\bc
9

C:\cygwin\bin>


Whereas I notice that Gow uses 1.06

And that does work with \r in cmd

C:\Program Files (x86)\Gow\bin>.\bc -v
bc 1.06

And  it works fine with \r

C:\Program Files (x86)\Gow\bin>echo 5+4|.\bc
9

C:\Program Files (x86)\Gow\bin>
