Embedded GLIBC (EGLIBC) was a variant of the GNU C Library (glibc), optimised for use in embedded devices, while still attempting to remain source- and binary-compatible with the standard glibc. The authors claim that EGLIBC was not intended to be a fork of glibc, but rather a variant, accepting patches that the core glibc developers may reject.On 6 May 2009, it was announced that Debian would move from the GNU C Library to EGLIBC, citing problems with the development process of glibc.
