 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 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.
 Profile names are of the form:  <CHOST>-<gcc version>
 For example:                    i686-pc-linux-gnu-3.2.1
