Tom Lane 7192865bdc Build backend/parser/scan.l and interfaces/ecpg/preproc/pgc.l standalone. 
Back-patch commit 72b1e3a21 into the pre-9.6 branches.

As noted in the original commit, this has some extra benefits: we can
narrow the scope of the -Wno-error flag that's forced on scan.c.  Also,
since these grammar and lexer files are so large, splitting them into
separate build targets should have some advantages in build speed,
particularly in parallel or ccache'd builds.

However, the real reason for doing this now is that it avoids symbol-
redefinition warnings (or worse) with the latest version of flex.
It's not unreasonable that people would want to compile our old branches
with recent tools.  Per report from Дилян Палаузов.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
