uClibc — A Tiny C Library
Available from http://www.uclibc.org/.
Designed to run on embedded system, so keeping the size down is an issue.
Currently runs on both standard Linux and MMU-less (uClinux), so there are a few memory allotment options internally and these can be configured.
Aims to be mostly compatible with GNU libc where practical.
Differences are partially documented and the gap is closing.
Sets some defines to claim to be glibc. This is because the defines are used in applications to provide checking for a particular interface, rather than a particular library. This "pretense" can be turned off with -D__FORCE_NOGLIBC. This whole hack is really a workaround for slightly broken coding practices, so is excusable.
