From 52ebc02e142d76325570f2edbf2032977e674d7d Mon Sep 17 00:00:00 2001
From: peter <peter@FreeBSD.org>
Date: Wed, 23 Jul 2003 04:53:47 +0000
Subject: Only provide one copy of the math functions.  If we provide a MD
 function, do not also provide a __generic_XXX version as well.  This is how
 we used to runtime select the generic vs i387 versions on the i386 platform.

This saves a pile of #defines in the src/math_private.h file to undo the
__generic_XXX renames in some of the *.c files.
