From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified
 gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream
 tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+/**
+ * The <code>string function converts an object to a string as follows:
+ * <ul>
+ * <li>A node-set is converted to a string by returning the string-value of
+ * the node in the node-set that is first in document order. If the node-set
+ * is empty, an empty string is returned.</li>
+ * <li>A number is converted to a string as follows
+ * <ul>
+ * <li>NaN is converted to the string NaN</li>
+ * <li>positive zero is converted to the string 0</li>
+ * <li>negative zero is converted to the string 0</li>
+ * <li>positive infinity is converted to the string Infinity</li>
+ * <li>negative infinity is converted to the string -Infinity</li>
+ * <li>if the number is an integer, the number is represented in decimal
+ * form as a Number with no decimal point and no leading zeros, preceded by
+ * a minus sign (-) if the number is negative</li>
+ * <li>otherwise, the number is represented in decimal form as a Number
+ * including a decimal point with at least one digit before the decimal
+ * point and at least one digit after the decimal point, preceded by a minus
+ * sign (-) if the number is negative; there must be no leading zeros before
+ * the decimal point apart possibly from the one required digit immediately
+ * before the decimal point; beyond the one required digit after the decimal
+ * point there must be as many, but only as many, more digits as are needed
+ * to uniquely distinguish the number from all other IEEE 754 numeric
+ * values.</li>
+ * </ul>
+ * </li>
+ * <li>The boolean false value is converted to the string false. The boolean
+ * true value is converted to the string true.</li>
+ * <li>An object of a type other than the four basic types is converted to a
+ * string in a way that is dependent on that type.</li>
+ * </ul>
+ * If the argument is omitted, it defaults to a node-set with the context
+ * node as its only member.
