make: *** [all-gdb] Error 2

The problem is simple.  In the library list, -lncurses appears after -ltermcap; it needs to appear before.

gdb 6.0 built on this platform   The library list for gdb 6.0 does not include -lncurses, so there is no ordering problem.


>How-To-Repeat:
Build gdb on native alphaev68-dec-osf5.1.
>Fix:
The problem is in configure.in.  The autoconf test for ncurses is before the autoconf test for termlib.  But the various autoconf macros build the library list in reverse order (lowest libraries first), so the the test for ncurses needs to come *after* the test for termlib.
