From 0623b9e6a9c3441427cf8c421bcc81d09e48fdc1 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sun, 6 Nov 2016 21:33:10 +0100 Subject: gconv.h: fix build with GCC 7 gconv.h is using a flex array to define the __gconv_info member in an invalid way, causing GCC 7 to issue an error: | In file included from ../include/gconv.h:1:0, | from ../sysdeps/unix/sysv/linux/_G_config.h:32, | from ../libio/libio.h:31, | from ../include/libio.h:4, | from ../libio/stdio.h:74, | from ../include/stdio.h:5, | from test-math-isinff.cc:22: | ../iconv/gconv.h:142:50: error: flexible array member '__gconv_info::__data' not at end of 'struct _IO_codecvt' | In file included from ../include/libio.h:4:0, | from ../libio/stdio.h:74, | from ../include/stdio.h:5, | from test-math-isinff.cc:22: | ../libio/libio.h:211:14: note: next member '_G_iconv_t _IO_codecvt::__cd_out' declared here | ../libio/libio.h:187:8: note: in the definition of 'struct _IO_codecvt' | In file included from ../include/gconv.h:1:0, | from ../sysdeps/unix/sysv/linux/_G_config.h:32, | from ../libio/libio.h:31, | from ../include/libio.h:4, | from ../libio/stdio.h:74, | from ../include/stdio.h:5, | from test-math-isinff.cc:22: | ../iconv/gconv.h:142:50: error: flexible array member '__gconv_info::__data' not at end of 'struct _IO_wide_data' | In file included from ../include/libio.h:4:0, | from ../libio/stdio.h:74, | from ../include/stdio.h:5, | from test-math-isinff.cc:22: | ../libio/libio.h:211:14: note: next member '_G_iconv_t _IO_codecvt::__cd_out' declared here | ../libio/libio.h:215:8: note: in the definition of 'struct _IO_wide_data' This is basically a revert to the code from 15 years ago.
