#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.
2000-08-02 18:28:18 +02:00
#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.
2000-08-22 07:10:20 +02:00
#include "thread.h"
Break out more header info into separate files. Use appropriate header files throughout. * shared.h: Remove. * cygwin_version.h: New file. * delqueue.h: New file. * environ.h: New file. * host_dependent.h: New file. * perprocess.h: New file. * registry.h: New file. * security.h: New file.

(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.
