* Makefile.in: Add rule for hpux-thread.o (needs special header files). * (SUBDIRS): Remove mswin. * Change procedure for creating init.c. Speeds things up quite a bit. * config.in configure configure.in: Check for select, poll. * Check for OSF header files before including hpux-thread.o. * Don't configure doc or testsuite when building under MSVC. * findvar.c value.h (read_register_pid write_register_pid): Make global. Needed for hppa-tdep.c. * (supply_register): Don't set pid to inferior_pid when supplying registers. * hppa-tdep.c (saved_pc_after_call): frame_saved_pc -> FRAME_SAVED_PC. * (frame_saved_pc): Change name to hppa_frame_saved_pc. * (hppa_pop_frame): Don't use a pid of 0 with target_write_pc. Use write_pc instead, which uses the correct pid. * (target_read_pc target_write_pc): Use read/write_register_pid instead of read/write_register to preserve the pid passed in. * inftarg.c (child_can_run): Add flag child_suppress_run to allow hpux-threads.c to override this as a runnable target. * config/pa/nm-hppah.h: Define target_new_objfile and target_pid_to_str. * config/pa/tm-hppa.h (FRAME_SAVED_PC): Use hppa_frame_saved_pc instead of frame_saved_pc. * config/m68k/tm-m68k.h: Define TARGET_M68K for Wingdb. * config/m68k/tm-monitor.h: Use FRAME_CHAIN_VALID_ALTERNATE, since we can't easily determine the start file bounds with ELF. * config/mips/tm-mips.h: Define TARGET_MIPS for Wingdb. * hpux-thread.c: New file for HPUX/OSF thread support. * osf-share/{README AT386/cma_thread_io.h HP800/cma_thread_io.h RIOS/cma_thread_io.h cma_attr.h cma_deb_core.h cma_debug_client.h cma_errors.h cma_handle.h cma_init.h cma_list.h cma_mutex.h cma_sched.h cma_semaphore_defs.h cma_sequence.h cma_stack.h cma_stack_int.h cma_tcb_defs.h cma_util.h}: New files for OSF thread support.

* Header file for generic list functions operating on singly linked

* IN THE ORDER IN WHICH THEY OCCURRED! WITHOUT SUCH READ/WRITE
