Wilcox" <AWilcox@Wilcox-Tech.com> -Date: Sat, 23 Jun 2018 17:57:48 -0500 -Subject: [PATCH] Don't use __extension__ in C++ code - -A few important notes: - -* __extension__ is a GNU C "alternate" keyword, not a C++ keyword.[1] - -* __extension__ is designed to work on "expressions"; it does work on - #include_next in C mode, but it has no effect in C++ mode; the - warning will still appear, if enabled, even with __extension__ - preceding #include_next. This is because #include_next is not - considered an expression in C++, so the compiler attaches - __extension__ to the first expression of the header. - -All of this leads us to a build failure while building at least all -Mozilla software. Moz has an alternate -isystem dir searched before -/usr/include that overrides some headers, including <features.h>. The -first statement in each of these headers is a #pragma, and since -__extension__ is looking for an expression, and #pragma is a "null" -expression, we end up with the following error: - -dist/system_wrappers/features.h:1:9: error: '#pragma' is not allowed here - -Since __extension__ has no effect on #include_next in C++ mode anyway, -and since it can cause breakage, this commit omits __extension__ in C++ -mode. - -[1]: https://gcc.gnu.org/onlinedocs/gcc-6.4.0/gcc/Alternate-Keywords.html ---- - include/poll.h | 2 ++ - include/stdio.h | 2 ++ - include/stdlib.h | 4 ++++ - include/string.h | 2 ++ - include/sys/select.h | 2 ++ - include/sys/socket.h | 2 ++ - include/unistd.h | 2 ++ - include/wchar.h | 8 ++++++++ - 8 files changed, 24 insertions(+) - -diff --git a/include/poll.h b/include/poll.h -index 7b42866..24691f1 100644 ---- a/include/poll.h -+++ b/include/poll.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_POLL_H - #define _FORTIFY_POLL_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <poll.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/stdio.h b/include/stdio.h -index b67f9ce..a965184 100644 ---- a/include/stdio.h -+++ b/include/stdio.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_STDIO_H - #define _FORTIFY_STDIO_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <stdio.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/stdlib.h b/include/stdlib.h -index 7ff5746..ef70995 100644 ---- a/include/stdlib.h -+++ b/include/stdlib.h -@@ -16,12 +16,16 @@ - #ifndef _FORTIFY_STDLIB_H - #define _FORTIFY_STDLIB_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <stdlib.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 - #if defined(_XOPEN_SOURCE) || defined(_GNU_SOURCE) || defined(_BSD_SOURCE) -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <limits.h> - #endif - -diff --git a/include/string.h b/include/string.h -index ff237b0..43c7485 100644 ---- a/include/string.h -+++ b/include/string.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_STRING_H - #define _FORTIFY_STRING_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <string.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/sys/select.h b/include/sys/select.h -index e4e398f..bcee8be 100644 ---- a/include/sys/select.h -+++ b/include/sys/select.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_SYS_SELECT_H - #define _FORTIFY_SYS_SELECT_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <sys/select.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/sys/socket.h b/include/sys/socket.h -index 7d3f023..ad6ab2d 100644 ---- a/include/sys/socket.h -+++ b/include/sys/socket.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_SYS_SOCKET_H - #define _FORTIFY_SYS_SOCKET_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <sys/socket.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/unistd.h b/include/unistd.h -index d3ab246..71dda84 100644 ---- a/include/unistd.h -+++ b/include/unistd.h -@@ -16,7 +16,9 @@ - #ifndef _FORTIFY_UNISTD_H - #define _FORTIFY_UNISTD_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <unistd.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 -diff --git a/include/wchar.h b/include/wchar.h -index 7394598..3cb6f92 100644 ---- a/include/wchar.h -+++ b/include/wchar.h -@@ -16,13 +16,21 @@ - #ifndef _FORTIFY_WCHAR_H - #define _FORTIFY_WCHAR_H - -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <limits.h> -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <stdlib.h> -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <string.h> -+#ifndef __cplusplus - __extension__ -+#endif - #include_next <wchar.h> - - #if defined(_FORTIFY_SOURCE) && _FORTIFY_SOURCE > 0 && defined(__OPTIMIZE__) && __OPTIMIZE__ > 0 --- -2.15.0 - |
