3 Added: gcc-config-1.5.1
4 Log:
5 Always sort runtime ld.so.conf paths and the install libgcc_s libraries based on version rather than defaulting to the selected profile #297685 by Scott McMurray. Fix gcc-config -E handling of GCC_SPECS #375091 by Bertrand Jacquin.

62 cat << "USAGE_END"
63 Usage: gcc-config [options] [CC Profile]
64 Change the current cc/gcc profile, or give info about profiles.
65
66 Options:
67 -C, --nocolor Disable color output
68 -O, --use-old Use the old profile if one was selected.
69 -f, --force Make sure all config files are regenerated.
70 -P, --use-portage-chost Only set to given profile if its CHOST is the
71 same as that set in /etc/portage/make.conf
72 (or one of other portage config files...).
73 -c, --get-current-profile Print current used gcc profile.
74 -l, --list-profiles Print a list of available profiles.
75 -S, --split-profile Split profiles into their components
76 -E, --print-environ Print environment that can be used to setup the
77 current gcc profile, or a specified one.
78 -B, --get-bin-path Print path where binaries of the given/current
79 profile are located.
80 -L, --get-lib-path Print path where libraries of the given/current
81 profile are located.
82
83 Profile names are of the form: <CHOST>-<gcc version>
84 For example: i686-pc-linux-gnu-3.2.1
