The algorithm computing daylight saving time incorrectly adds a day for each month after January for leap years.

2011-09-15Defeat compiler optimization which assumes function addresses are never NULLDenys Vlasenko
From email: A warning for people who can be hit by the same or similar issue: gcc 4.1.2 with -march=i486 here with -Os and even with -O2 or -O is "optimizing away" the check if (_stdio_term) in libc/stdlib/_atexit.c which results in a "call 0" and a segfault at exit if you do not happen to link in stdio.

2011-08-26inet: build all res_* and ns_* functions conditionallyDaniel Mack
This patch changes the build system so that all DNS resolver related functions (ie, those starting with dn_, ns_ and res_) are only built if UCLIBC_HAS_RESOLVER_SUPPORT is set. This means that the libc will lack support for things that existed in the library before unless this new config option is set. On the other hand, if users really need support for resolver functions, they now get a more complete set, and the library is smaller than before it is deselected.

2011-06-29libc: add missing lock initialization in vswprintfMaksim Rayskiy
Unlike vsnprintf, vswprintf does not properly initialize locking elements of FILE structure, which in some unfortunate cases can result in lockups in _vfwprintf_internal. Interesting, the initialization code was removed in 2a915734a32c5aec9a6a76c13bcb074d30e64171 at the same time as it was added to vsnprintf.
