+Several changes have been made for klibc:
+
+* The build system is changed from autotools to kbuild, with a static config.h
+* Use of strtod() is guarded by HAVE_STRTOD, which we don't define
+* The built-in times command, which requires floating-point support, is
+  disabled
+* The signal_names[] array is replaced by a signal_name() function using
+  klibc's own signal name array.  decode_signal() is changed similarly.
+* The read built-in implements the -t option like bash
+* mktokens is modified to support out-of-tree builds
+* mkbuiltins is modified to sort with LC_ALL=C
+* Some header files have header guards added
+* Changelog and some manual pages are omitted
+* Automatic whitespace fixups
+
