thread attributes for the main thread.
Add emulation of native threads (libc_r) method of getting the current
thread attributes (pthread_attr_get_np()) and adjust emulation of native
threads pthread_attr_getstackaddr() to return bottom of stack instead of
top of stack.
Correct emulation of native threads pthread_mutexattr_settype() when
selecting recursive mutexes. Previously, the argument conversion before
calling the linuxthreads version of pthread_mutexattr_setattr() ended up
selecting errorcheck mutexes instead of recursive mutexes.
Add sys/_pthreadtypes.h to allow compilation on FreeBSD >= 6.0.
Initialize signal trampoline variables earlier to avoid race in wrapper
around sigaction.
Fix known API wrapper bugs.
Port compile time options:
Add option for using an alternate restart signal instead of SIGUSR2.
Add options for adjustment of maximum thread stack size and maximum
number of threads.
Make all options start with LINUXTHREADS_

Drop use of deprecated AINC variable.
Reenable use of ld(1) to restore the LINUXTHREADS_WRAP_API option.
Rename __thread to __xthread in prototypes to avoid conflict with
new gcc keyword.

functions providing most of the native threads API while avoiding name
clashes by transparently prefixing all function names that directly
provide the linuxthreads API.
Defining INSTALL_LIBLTHREAD_PIC_ARCHIVE causes installation and
registration of PIC archive for liblthread, which can be used to
generate a shared liblthread library for a different gcc installation.

- Block cancel signal while creating new thread to avoid losing
the signal.
- Terminate the process with _exit(1) if it's unsafe to continue
calling atexit functions and destructors.
pthread_attr_t is provided as argument to pthread_create.
liblgcc_r_pic.a no longer exists.
Put the liblgcc_r.a version of __get_eh_info() and __register_frame_info()
into the shared linuxthreads library to avoid using the incompatible
libgcc.a version. Shared libraries that use exceptions still represent a
problem if linked before the linuxthreads library.
Compile liblgcc_r.a before the main linuxthreads library to provide
the object files that contains __get_eh_info() and __register_frame_info().
Add minimal wrappers for native thread library functions used by
5.0-CURRENT libc. The wrappers try to call corresponding functions
in the linuxthreads library after performing argument conversion.

state. Instead, use a simple spinlock-based rwlock implementation.
Make minor cancellation cleanups.
which is rather tightly coupled with GNU libc, unlike the older version
of this port.
LinuxThreads has added many features since it was integrated with GNU libc,
which means that a number of interfaces that were borrowed from libc_r are
no longer needed.
This updated port required a lot of reworking of the port, so there are
likely to be new bugs.

Native FreeBSD port of the linuxthreads library
Includes added files and stuff you need to add to the rest of your system.
This is for -current I'm sure Richard's older version might be
a good place to start for a 3.x version.
