Package: emacs
Severity: wishlist

It is possible to build a separate terminfo library from the ncurses
sources by configuring ncurses with the "--with-termlib" option.  This
library is usually called libtinfo, and several GNU/Linux distributions
are using this option; Fedora since Version 7 (May 2007), Ubuntu since
version 11.10 (to be released tomorrow) and Debian in testing/unstable
for two weeks.

If ncurses is built this way, Emacs only needs symbols from libtinfo,
but with the current `configure' script links against libncurses
unnecessarily.  It would be nice if `configure' were looking for
libtinfo and prefer to use -ltinfo over -lncurses.

Hello.

Is this regarded as a feature, for after the release?

It's not particularly urgent, since libncurses is rather ubiquitous on
GNU/Linux, and the extra linkage probably does not have much impact on
startup time and memory footprint.
