>Description:
In GDB 5.0 release, the linux-threads.c module
was provided for debugging LinuxThreads-style
multithreaded programs.
However, in the current tree, this module is disabled.

We have multithreaded applications with a home-grown
thread library that use clone()
system call, and use the linux-threads.c API
for making GDB threads-aware.  For various reasons,
we cannot use Linux's libpthread (lin-threads.c module).
We also cannot use lin-lwp.c module.

I'd like linux-threads.c turned back on.  It can be
lower priority than lin-threads.  That is,
  try lin-threads.  if fails,
  try linux-threads.  if fails,
  try lin-lwp.
