   On NetBSD-1.4.2 is that the link test works with -ledit, and indeed
   psql built without -ltermcap will even run non-interactively (I loaded
   a database with it) but it fails when running interactively.
   
   config.log:
   
   configure:3143: checking for readline
   configure:3165: gcc -o conftest -O2 -pipe     conftest.c -lreadline  1>&5
   ld: -lreadline: no match
   collect2: ld returned 1 exit status
   configure: failed program was:
   #line 3154 "configure"
   #include "confdefs.h"
   /* Override any gcc2 internal prototype to avoid an error.  */
   /* We use char because int might match the return type of a gcc2
       builtin and then its argument prototype would still apply.  */
   char readline();
   
   int main() {
   readline()
   ; return 0; }
   configure:3165: gcc -o conftest -O2 -pipe     conftest.c -ledit  1>&5
   configure:3192: checking for library containing using_history
   configure:3210: gcc -o conftest -O2 -pipe     conftest.c -ledit  1>&5
   ...
   
   It would be nicer if the link failed. :-(
   
   Actually running the program above:
   
   /usr/libexec/ld.so: Undefined symbol "_tgetent" called from
   conf:/usr/lib/libed\ it.so.2.2 at 0x4002d2ac
   
   ldd doesn't show problems:
   
   conf:
           -ledit.2 => /usr/lib/libedit.so.2.2 (0x4001b000)
           -lc.12 => /usr/lib/libc.so.12.40 (0x4002f000)
   
   I'm now out of my depth with both configure and linker behaviour. :-(

   This looks to be an oddly behaving linker.  Maybe this is a better
   question for a netbsd user forum.

   How about ldd libedit?
