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.

+# This shell script produces a header file fragment that defines
+# SYSROOT_SUFFIX_SPEC.  It assumes that the sysroots will have the same
+# structure and names used by the multilibs.
+
+# Invocation:
+#   print-sysroot-suffix.sh \
+#          MULTILIB_OSDIRNAMES \
+#          MULTILIB_OPTIONS \
+#          MULTILIB_MATCHES \
+#      > t-sysroot-suffix.h
+
+# The three options exactly correspond to the variables of the same
+# names defined in the tmake_file fragments.
+
+# Example:
+#   sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" ""
+# =>
+#   #undef SYSROOT_SUFFIX_SPEC
+#   #define SYSROOT_SUFFIX_SPEC "" \
+#   "%{a:" \
+#     "%{b:A/b/;" \
+#     "c:A/c/;" \
+#     "d:A/d/;" \
+#     ":A/};" \
+#   ":}"
+
+# The script uses temporary subscripts in order to permit a recursive
+# algorithm without the use of functions.
