>Description:
bc(1) should prints error message to stderr. For example,
UNIX (Heirloom) bc prints to stderr
$ echo ':' | /usr/local/heirloom/usr/5bin/bc > /dev/null
syntax error on line 1, teletype
$ echo ':' | /usr/local/heirloom/usr/5bin/bc 2> /dev/null
$
GNU bc prints to stderr
$ echo ':' | /usr/local/bin/bc > /dev/null
(standard_in) 1: illegal character: :
$ echo ':' | /usr/local/bin/bc 2> /dev/null
$
FreeBSD (OpenBSD) bc prints to stdout
$ echo ':' | /usr/bin/bc > /dev/null
$ echo ':' | /usr/bin/bc 2> /dev/null
bc: stdin:1: illegal character: : unexpected
$
