2012-06-15cleanup fork()Peter S. Mazinger
Keep only fork (and it's hidden variant) and __libc_fork. Common __libc_fork prototype in unistd.h. Get rid of __fork, by changing HIDDEN_JUMPTARGET(__fork) to use fork I can't see the reason to have fork() in libpthread, but kept it for now making __fork static in these files.

2012-04-22linuxthreads.old: only declare __pthread_xxx funcs hidden inside of libpthreadMike Frysinger
These stubs get used in libc as forwarding funcs, so we don't want them labeled as hidden. Otherwise, attempting to use them in other libraries (like libdl) will result in references to symbols that only libpthread provides. Such as: /usr/bin/python2.6: can't resolve symbol '__pthread_mutex_lock' in lib '/lib/libdl.so.0'. This also brings the old code in line with the newer linuxthreads.

2012-01-14linuxthreads/signals: do not restore handler for invalid signalMarkos Chandras
Invalid signals have no handlers so when trying to restore the old handler to a bad signal a SIGSEGV occurs. This is because the library tries to store the old handler to an invalid memory area where it things the bad signal lives.

2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.
