+Usage: gcc-config [options] [CC Profile]
+Change the current cc/gcc profile, or give info about profiles.
+
+Options:
+ -C, --nocolor Disable color output
+ -O, --use-old Use the old profile if one was selected.
+ -f, --force Make sure all config files are regenerated.
+ -P, --use-portage-chost Only set to given profile if its CHOST is the
+ same as that set for portage in /etc/make.conf
+ (or one of other portage config files...).
+ -c, --get-current-profile Print current used gcc profile.
+ -l, --list-profiles Print a list of available profiles.
+ -S, --split-profile Split profiles into their components
+ -E, --print-environ Print environment that can be used to setup the
+ current gcc profile, or a specified one.
+ -B, --get-bin-path Print path where binaries of the given/current
+ profile are located.
+ -L, --get-lib-path Print path where libraries of the given/current
+ profile are located.
+ -X, --get-stdcxx-incdir Print path where g++ include files of the
+ given/current profile are located.
+
+Profile names are of the form: <CHOST>-<gcc version>
+For example: i686-pc-linux-gnu-3.2.1

+Usage: gcc-config [options] [CC Profile]
+Change the current cc/gcc profile, or give info about profiles.
+
+Options:
+ -C, --nocolor Disable color output
+ -O, --use-old Use the old profile if one was selected.
+ -f, --force Make sure all config files are regenerated.
+ -P, --use-portage-chost Only set to given profile if its CHOST is the
+ same as that set in /etc/portage/make.conf
+ (or one of other portage config files...).
+ -c, --get-current-profile Print current used gcc profile.
+ -l, --list-profiles Print a list of available profiles.
+ -S, --split-profile Split profiles into their components
+ -E, --print-environ Print environment that can be used to setup the
+ current gcc profile, or a specified one.
+ -B, --get-bin-path Print path where binaries of the given/current
+ profile are located.
+ -L, --get-lib-path Print path where libraries of the given/current
+ profile are located.
+
+Profile names are of the form: <CHOST>-<gcc version>
+For example: i686-pc-linux-gnu-3.2.1

+Usage: gcc-config [options] [CC Profile]
+Change the current cc/gcc profile, or give info about profiles.
+
+Options:
+ -C, --nocolor Disable color output
+ -O, --use-old Use the old profile if one was selected.
+ -f, --force Make sure all config files are regenerated.
+ -P, --use-portage-chost Only set to given profile if its CHOST is the
+ same as that set in /etc/portage/make.conf
+ (or one of other portage config files...).
+ -c, --get-current-profile Print current used gcc profile.
+ -l, --list-profiles Print a list of available profiles.
+ -S, --split-profile Split profiles into their components
+ -E, --print-environ Print environment that can be used to setup the
+ current gcc profile, or a specified one.
+ -B, --get-bin-path Print path where binaries of the given/current
+ profile are located.
+ -L, --get-lib-path Print path where libraries of the given/current
+ profile are located.
+
+Profile names are of the form: <CHOST>-<gcc version>
+For example: i686-pc-linux-gnu-3.2.1

+Subject: [PATCH] Ignore whitespace when diffing test results.
+
+The amount of whitespace output by ebegin/eend from gentoo-functions
+is dynamic (seems to be dependent on terminal width). Since we can't
+predict this we have to ignore all whitespace differences.
