Subject: Patch to get bc 1.06 to compile under Cygwin with readline library.

I downloaded and installed the Cygwin source code to bc 1.06, but it
would not build under Cygwin 1.3.12-2 when configured with

	--enable-readline

unless I made a small change to bc/scan.l (which may or may not be the
right way to fix the compiler error about symbol "readline" having
conflicting definitions, one in scan.l and one in
/usr/include/readline/readline.h).

The patch is below.  Hope this helps.
