* remove ucontext.h and guard sigstack structure with SUSV4_LEGACY and ↵Peter S. Mazinger2011-03-031-1/+0
| | | | | | | | | | STRICT_HEADERS Remove ucontext.h if SUSV4_LEGACY is not set and fix it's references. Guard sigstack structure with SUSV4_LEGACY and STRICT_HEADERS. Disable sigstack function prototype, it is not provided by uClibc. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>

* linuxthreads: Fix compilation breakageMatt Fleming2010-12-231-7/+4
| | | | | | | | | With commit "resolv.c: add support for per thread res_state" (aab4df0fb51660300559f5f29290709db2f7bfee) _res symbol is now marked as hidden in an attempt to make the resolver per-thread.

* mips: fix errno setting after syscallAlexander Gordeev2010-10-271-1/+2
| | | | | | | | | | | | | | | If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

* | nptl: proper soname handlingNatanael Copa2010-04-221-3/+3
|/ | | | | | | | | | | Since sublevel releases are not ABI compatible we need to adjust the soname to include the sublevel version. This makes it possible to install ABI incompatible versions of the library side by side so clean upgrades are possible.

| | | | | | | | | Previously the old headers were left in include/ leading to spurious compile failures. This is ugly as it can get (we resort to sneaking -L in for the moment) but good enough for now. The worst thing which can happen is that we ln these headers once per invocation of make, nothing more. If some installation of make(1) complains about the "-L" then wrap it in ifneq ($(findstring check-symlink,$(.FEATURES)),)
