2011-11-23libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso
On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.

The algorithm computing daylight saving time incorrectly adds a day for each month after January for leap years. The clock shift from/to DST can be delayed if the last Sunday of a transition month is exactly seven days before the first of the following month. This change adds a day for the February month only.

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.
