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_
Note that complete FreeBSD source matching userland must be installed
in /usr/src when compiling this port.
functions providing most of the native threads API while avoiding name
clashes by transparently prefixing all function names that directly
provide the linuxthreads API.
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.
