I have just uploaded Embedded GLIBC (EGLIBC) into the archive (it is currently waiting in the NEW queue), which will soon replace the GNU C Library (GLIBC).

The EGLIBC is a variant of the GLIBC which stays source and binary compatible with the original GLIBC. While primarily targeted for embedded architectures, it has some really nice points:

We do not use some of these features yet, but this upload is a first step. From the user point of view, the package names are unchanged (except the source package and the binary package containing the sources) so no transition is needed.
