The attached patch corrects two problems with autoconfiguration of

psql in Postgres 6.3.2.  Both of these problems were complained of
recently in pgsql-questions:

1. In the right circumstances, psql.c will fail to compile due to
trying
   to include a nonexistent <history.h>.  (Thread "Compile-time
   error" around 17 Apr 98.) 2. In other circumstances, psql will
compile but does not provide
   command history capability, even though the underlying readline
   library supports it.  (Various threads, most recently "query
   repetition in psql" around 29 Apr.)
