/* init.cc for WIN32.
* exceptions.cc (interruptible): Change method for determining if something is interruptible. (call_handler): Avoid suspending a thread if it owns a mutex. Only set signal_arrived if the thread was actually interrupted. (events_init): Initialize module information needed by interruptible(). (sigdelayed): Don't call sig_dispatch_pending since it could screw up * init.cc (dll_entry): Record module handle of main for use by interruptible(). (proc_subproc): Reorganize handling of terminated child so that the bulk of the processing comes from the signal thread. (wait_sig): Force processing of waiting threads if SIGCHLD is not processed. * sync.cc (muto::release): Set tid == 0 after lock is released or signal processor will be confused.

#include "winsup.h"
* winsup.h: take out protections of environ, errno, allow C use * *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__); use cur_environ() instead of just environ * times.cc: remove import protections * glob.c: add winsup.h * localtime.c: ditto * smallprint.c: ditto * Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.

#include <stdlib.h>
* winsup.h: Eliminate inclusion of most of the cygwin .h files. Use .h files only in sources which require them. * Makefile.in: Generate dependencies with -MD option.
