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 + |
