commit 353ea2d106a51cfd1680f7d351f35eb8f69c9248
Author: Eli Zaretskii <eliz@gnu.org>
Date: Fri May 3 10:55:33 2019 +0300
On MS-Windows, define _WIN32_WINNT in a single common place.
This changeset defines _WIN32_WINNT to at least 0x0501, the level
of Windows XP, unless defined to a higher level, in a single
place. It then removes all the overrides of _WIN32_WINNT in
individual files as no longer needed. Doing this also solves
compilation of windows-nat.c with mingw.org's MinGW, as that
file uses CONSOLE_FONT_INFO which needs the XP level to become
exposed in the Windows headers, while mingw.org defaults to
Windows 9X.
gdb/ChangeLog:
2019-05-03 Eli Zaretskii <eliz@gnu.org>
* common/common-defs.h [__MINGW32__ || __CYGWIN__]: Define
_WIN32_WINNT to the XP level, unless already defined to a higher
level.
* unittests/parse-connection-spec-selftests.c:
* ser-tcp.c:
* common/netstuff.c [USE_WIN32API]: Remove the _WIN32_WINNT
override.
gdb/gdbserver/ChangeLog:
2019-05-03 Eli Zaretskii <eliz@gnu.org>
* remote-utils.c:
* gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override.
