Oops. You're right. There is a local patch to symtab.c that I'd
forgotten about. It was submitted by Jim Blandy but (apparently) never
applied. I guess it's time to research this.

In any event, your advice is still valid. There's no reason to use the
cygwin sources of gdb if you're trying to build a gdb for another
platform.

It seems like the error is coming from readline/configure.
