 * Subset Libc Specification - CELF once considered the possibility of creating a subset libc specification.  Some companies have also examined the possibility of modularizing glibc, so that parts of it can be made configurable.  Preliminary research indicates that this could be a very difficult thing, since glibc has very messy function interdependencies.
