Contains the standard libraries that are used by nearly all programs on the system. this package includes shared versions of the standard c library and the standard math library, as well as many others.

this set of libraries is optimized for i686 machines, and will only be used if you are running a 2.6 kernel on an i686 class cpu (check the output of `uname -m'). this includes pentium pro, pentium ii/iii/iv, celeron cpu's and similar class cpu's (including clones such as amd athlon/opteron, via c3 nehemiah, but not via c3 ezra).
