Apparently, it is a bug that it is defined in *any* strict ANSI/ISO mode, be it C or C++. Related to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11196 But for this particular issue, note: $ /usr/bin/i586-mingw32msvc-g++ -std=gnu++0x -E -dM foo.c|grep -i 'M_PI ' #define M_PI 3.14159265358979323846 So maybe you would have more luck with "-std=gnu++0x" than with "-std=c++0x"? -- Lionel _______________________________________________ LibreOffice mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libreoffice
