libc6-i686 2.4-1ubuntu12.3 (i386 binary) in ubuntu edgy

 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 Ezla).
 .
 This package includes support for NPTL.
 .
 WARNING: Some third-party binaries may not work well with these libraries.
 Most notably, IBM's JDK. If you experience problems with such
 applications, you will need to remove this package.
