Tom Lane 65abaab547 Further adjust degree-based trig functions for more portability. 
The last round didn't do it.  Per Noah Misch, the problem on at least
some machines is that the compiler pre-evaluates trig functions having
constant arguments using code slightly different from what will be used
at runtime.  Therefore, we must prevent the compiler from seeing constant
arguments to any of the libm trig functions used in this code.

The method used here might still fail if init_degree_constants() gets
inlined into the call sites.  That probably won't happen given the large
number of call sites; but if it does, we could probably fix it by making
init_degree_constants() non-static.  I'll avoid that till proven
necessary, though.

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/.
