* Makefile.in (CLIBS): Reorder to make Lynx ld happy.
* (HFILES): New file thread.h.
* (OBS): New file thread.c.
* configure.in: Host config for Lynx/386.
* fork-child.c (fork_inferior): Call init_thread_list().
* infrun.c (resume): Add pid to invocation of target_resume().
* (wait_for_inferior): Pay attention to pid from target_wait().
Multi-threading code now uses this to determine what to do.
* inftarg.c (child_wait): Conditionalize based on CHILD_WAIT macro.
Use target_pid_to_str() macro throughout when printing pid.
* inferior.h (child_resume): Add pid to prototype.
* hppab-nat.c hppah-nat.c infptrace.c (child_resume): Pass in pid as
argument, instead of using inferior_pid.
* procfs.c (procfs_resume): Pass in pid as argument. Ignored for
now. Use target_pid_to_str() macro throughout for printing process id.
* remote-adapt.c (adapt_resume): Pass in pid as argument.
* remote-eb.c (eb_resume): Pass in pid as argument.
* remote-es.c (es1800_resume): Pass in pid as argument.
* remote-hms.c (hms_resume): Pass in pid as argument.
* remote-mips.c (mips_resume): Pass in pid as argument.
* remote-mm.c (mm_resume): Pass in pid as argument.
* remote-monitor.c (monitor_resume): Pass in pid as argument.
* remote-nindy.c (nindy_resume): Pass in pid as argument.
* remote-sa.sparc.c (remote_resume): Pass in pid as argument.
* remote-sim.c (rem_resume): Pass in pid as argument.
* remote-sp64sim.c (simif_resume): Pass in pid as argument.
* remote-st.c (st2000_resume): Pass in pid as argument.
* remote-udi.c (udi_resume): Pass in pid as argument.
* remote-vx.c (vx_resume): Pass in pid as argument.
* remote-z8k.c (rem_resume): Pass in pid as argument.
* remote.c (remote_resume): Pass in pid as argument.
* solib.c (solid_create_inferior_hook): Pass inferior_pid to
target_resume().
* target.c (normal_pid_to_str): New routine to print out process
ID normally.
* target.h (struct target_ops): Add pid to prototype at
to_resume(). (target_resume): Add pid argument.
* (target_pid_to_str): Default definition for normal type pids.
* thread.c, thread.c: New modules for multi thread/process control.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
