Handling of -Wno-pointer-sign when used with g++ is not consistent with other C specific warning option (at least -Wstrict-prototypes -Wdeclaration-after-statement) May I suggest to also emit a warning instead of an error as many people use CXXFLAGS= $(CFLAGS) + $(c++ specific options) cc1plus: warning: command line option "-Wstrict-prototypes" is valid for Ada/C/ObjC but not for C++ cc1plus: warning: command line option "-Wdeclaration-after-statement" is valid for C/ObjC but not for C++ cc1plus: error: unrecognized command line option "-Wno-pointer-sign"
Confirmed. Only a 3.4 regression. 4.0.0 and 4.0.1 (and the mainline) produces: cc1plus: warning: command line option "-Wno-pointer-sign" is valid for C/ObjC but not for C++ 3.0.4 produced no warning or error. 2.95.3 did not have "-Wpointer-sign" so we errored out when using "-Wno-pointer-sign".
Yes you are right g++ is : g++ -v Reading specs from /usr/lib/gcc/i486-linux-gnu/3.4.5/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr --libexecdir=/usr/lib --with-gxx-include-dir=/usr/include/c++/3.4 --enable-shared --with-system-zlib --enable-nls --without-included-gettext --program-suffix=-3.4 --enable-__cxa_atexit --enable-libstdcxx-allocator=mt --enable-clocale=gnu --enable-libstdcxx-debug --enable-java-gc=boehm --enable-java-awt=gtk --disable-werror i486-linux-gnu Thread model: posix gcc version 3.4.5 20050706 (prerelease) (Debian 3.4.4-5) Thanks for you quick response
3.4 does not contain such option at all. I wonder in what way 3.0.4 was special in this regard ;)
