* nt/inc/ms-w32.h (struct timespec): Don't declare if
__struct_timespec_defined is defined.

* nt/emacs-x86.manifest (asmv3:windowsSettings): Add dpiAware.
* nt/emacs-x64.manifest (asmv3:windowsSettings): Add dpiAware.
This avoids Windows entering compatibility mode for Emacs,
which causes fonts to look less nice.

Copyright-paperwork-exempt: yes

* nt/gnulib.mk (libgnu_a_SOURCES): Add get-permissions.c back.
(gnulib module qcopy-acl): Add back, as it is harmless.  This
minimizes differences wrt lib/gnulib.mk.

* nt/gnulib.mk (libgnu_a_SOURCES): Remove get-permissions.c and
set-permissions.c, as they don't compile on MinGW.
(gnulib module qcopy-acl): Remove, as it needs set-permissions.c.

This incorporates:
2015-05-27 qacl: Reimplement qset_acl and qcopy_acl (Bug#20666)
2015-05-27 file-has-acl: Split feature tests again (Bug#20667)
2015-05-27 string: fix build failure on BSD/OSX with FORTIFY_SOURCE
2015-05-26 stdio: limit __gnu_printf__ witness to gcc 4.4+
2015-05-26 inttypes: force correct mingw PRIdMAX even without <stdio.h>
2015-05-26 stdio: fix probe on mingw under gcc 5.1
* admin/merge-gnulib (GNULIB_MODULES):
Replace qacl with qcopy-acl, since we don't need the rest of qacl.
* doc/misc/texinfo.tex, lib/acl-internal.c, lib/acl-internal.h:
* lib/inttypes.in.h, lib/qcopy-acl.c, lib/qset-acl.c:
* lib/string.in.h, m4/acl.m4, m4/stdio_h.m4:
Get latest versions from gnulib.
* lib/get-permissions.c, lib/set-permissions.c: New files.
* lib/gnulib.mk, m4/gnulib-comp.m4:
Regenerate.
* nt/gnulib.mk: Merge lib/gnulib.mk changes by hand.

* nt/gnulib.mk (libgnu_a_SOURCES): Replace file-has-acl.c with
acl-internal.c.

 Based on ideas from Kim F. Storm <storm@cua.dk>, see
 http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg00873.html.

 src/w32proc.c (reader_thread): If the FILE_CONNECT flag is set, call
 '_sys_wait_connect'.  If it returns STATUS_CONNECT_FAILED, exit
 the thread with code 2.
 (sys_select): Support 'wfds' in addition to 'rfds'.  If a
 descriptor in 'wfds' has its bit set, but the corresponding
 fd_info member doesn't have its FILE_CONNECT flag set, ignore the
 descriptor.  Otherwise, acknowledge a successful non-blocking
 connect by resetting the FILE_CONNECT flag and setting cp->status
 to STATUS_READ_ACKNOWLEDGED.
 src/w32.h (STATUS_CONNECT_FAILED): New enumeration value.
 (struct _child_process): New member 'errcode'.
 (FILE_CONNECT): New flag.
 (_sys_wait_connect): Add prototype.
 src/w32.c (pfn_WSAEnumNetworkEvents): New function pointer.
 (init_winsock): Load WSAEnumNetworkEvents from winsock DLL.
 (set_errno): Map WSAEWOULDBLOCK and WSAENOTCONN.
 (sys_connect): Support non-blocking 'connect' calls by setting the
 FILE_CONNECT flag in the fd_info member and returning EINPROGRESS.
 (_sys_read_ahead): Add debug message if this function is called
 for a descriptor that waits for a non-blocking connect to complete.
 (_sys_wait_connect): New function.
 (sys_read): Support STATUS_CONNECT_FAILED.  Return the error code
 recorded by _sys_wait_connect when the non-blocking connect
 failed.  Don't call WSAGetLastError before a call to set_errno had
 a chance to use its value, since WSAGetLastError clears the last
 error.

 nt/inc/ms-w32.h (BROKEN_NON_BLOCKING_CONNECT): Don't define.
