From 353ea2d106a51cfd1680f7d351f35eb8f69c9248 Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Fri, 3 May 2019 10:55:33 +0300 Subject: [PATCH] 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 * 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 * remote-utils.c: * gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override. --- gdb/ChangeLog | 9 +++++++++ gdb/common/common-defs.h | 14 ++++++++++++++ gdb/common/netstuff.c | 4 ---- gdb/gdbserver/ChangeLog | 5 +++++ gdb/gdbserver/gdbreplay.c | 4 ---- gdb/gdbserver/remote-utils.c | 4 ---- gdb/ser-tcp.c | 4 ---- gdb/unittests/parse-connection-spec-selftests.c | 4 ---- 8 files changed, 28 insertions(+), 20 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index efe07af..4820ebf 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,14 @@ 2019-05-03 Eli Zaretskii + * 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. + * symfile.c (find_separate_debug_file): Remove colon from the drive spec of DOS/Windows file names of the target, so that the file name produced from DEBUGDIR and the target's directory will diff --git a/gdb/common/common-defs.h b/gdb/common/common-defs.h index 6b1f004..8c16492 100644 --- a/gdb/common/common-defs.h +++ b/gdb/common/common-defs.h @@ -72,6 +72,20 @@ #define _FORTIFY_SOURCE 2 #endif +/* We don't support Windows versions before XP, so we define + _WIN32_WINNT correspondingly to ensure the Windows API headers + expose the required symbols. */ +#if defined (__MINGW32__) || defined (__CYGWIN__) +# ifdef _WIN32_WINNT +# if _WIN32_WINNT < 0x0501 +# undef _WIN32_WINNT +# define _WIN32_WINNT 0x0501 +# endif +# else +# define _WIN32_WINNT 0x0501 +# endif +#endif /* __MINGW32__ || __CYGWIN__ */ + #include #include #include diff --git a/gdb/common/netstuff.c b/gdb/common/netstuff.c index 27fdc73..b192de7 100644 --- a/gdb/common/netstuff.c +++ b/gdb/common/netstuff.c @@ -21,10 +21,6 @@ #include #ifdef USE_WIN32API -#if _WIN32_WINNT < 0x0501 -# undef _WIN32_WINNT -# define _WIN32_WINNT 0x0501 -#endif #include #else #include diff --git a/gdb/gdbserver/ChangeLog b/gdb/gdbserver/ChangeLog index 2985281..82278e7 100644 --- a/gdb/gdbserver/ChangeLog +++ b/gdb/gdbserver/ChangeLog @@ -1,3 +1,8 @@ +2019-05-03 Eli Zaretskii + + * remote-utils.c: + * gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override. + 2019-04-19 Tom Tromey * server.c (struct vstop_notif): Derive from notif_event. diff --git a/gdb/gdbserver/gdbreplay.c b/gdb/gdbserver/gdbreplay.c index ca0a9d3..2800e78 100644 --- a/gdb/gdbserver/gdbreplay.c +++ b/gdb/gdbserver/gdbreplay.c @@ -45,10 +45,6 @@ #endif #if USE_WIN32API -#if _WIN32_WINNT < 0x0501 -# undef _WIN32_WINNT -# define _WIN32_WINNT 0x0501 -#endif #include #endif diff --git a/gdb/gdbserver/remote-utils.c b/gdb/gdbserver/remote-utils.c index 903d773..1d27ea3 100644 --- a/gdb/gdbserver/remote-utils.c +++ b/gdb/gdbserver/remote-utils.c @@ -63,10 +63,6 @@ #include #if USE_WIN32API -#if _WIN32_WINNT < 0x0501 -# undef _WIN32_WINNT -# define _WIN32_WINNT 0x0501 -#endif #include #endif diff --git a/gdb/ser-tcp.c b/gdb/ser-tcp.c index 039b043..927a285 100644 --- a/gdb/ser-tcp.c +++ b/gdb/ser-tcp.c @@ -39,10 +39,6 @@ #include "common/gdb_sys_time.h" #ifdef USE_WIN32API -#if _WIN32_WINNT < 0x0501 -# undef _WIN32_WINNT -# define _WIN32_WINNT 0x0501 -#endif #include #ifndef ETIMEDOUT #define ETIMEDOUT WSAETIMEDOUT diff --git a/gdb/unittests/parse-connection-spec-selftests.c b/gdb/unittests/parse-connection-spec-selftests.c index a4beb66..915aa66 100644 --- a/gdb/unittests/parse-connection-spec-selftests.c +++ b/gdb/unittests/parse-connection-spec-selftests.c @@ -22,10 +22,6 @@ #include "common/netstuff.h" #include "diagnostics.h" #ifdef USE_WIN32API -#if _WIN32_WINNT < 0x0501 -# undef _WIN32_WINNT -# define _WIN32_WINNT 0x0501 -#endif #include #else #include -- 2.7.4
