gdb/
* gdbthread.h (currently_stepping): New declaration.
* infrun.c (currently_stepping): Remove the forward declaration.
(currently_stepping): Make it global.
* linux-nat.c (resume_callback) <lp->stopped && lp->status == 0>: New
variables tp and step, initialized them. Pass STEP to to_resume.
Print also possibly "PTRACE_SINGLESTEP" if STEP. Initialize LP->STEP.
* remote.c (currently_stepping_callback): New.
(remote_vcont_resume)
<ptid_equal (ptid, minus_one_ptid) || ptid_is_pid (ptid)>:
New variable tp. Call currently_stepping_callback and step such
thread.
gdb/testsuite/
* gdb.threads/sigstep-threads.exp: New file.
* gdb.threads/sigstep-threads.c: New file.
