With the configure.ac change, how can that happen?

No "gdb/" prefix.

I'm confused on the predicate here. How can we tell
from $prefer_curses that the curses library doesn't include
termcap? AFAICS, if the TUI is enabled, it'll always be
"yes". But isn't that the case where you _don't_
want windows-termcap.o? And shouldn't this be checking
$curses_found?

All files in gdb/ should start with "defs.h" instead.
