I just installed gcc/mingw 4.8.3-2 and have all versions from 4.7.3 to 4.8.3-2 but (I think) only libraries and etc. for 4.8.3-2. Am I responsible for deleting these older references? Will these older references work with the newer libraries? These are the programs I have (for i in `ls /bin/i686* ls/bin/x86*`; do $i --version; done | grep GCC) i686-pc-cygwin-c++ (GCC) 4.8.2 i686-pc-cygwin-cpp (GCC) 4.8.2 i686-pc-cygwin-g++ (GCC) 4.8.2 i686-pc-cygwin-gcc (GCC) 4.8.2 i686-pc-cygwin-gcc-4.8.2 (GCC) 4.8.2 GNU Fortran (GCC) 4.8.2 i686-pc-mingw32-c++ (GCC) 4.7.3 i686-pc-mingw32-cpp (GCC) 4.7.3 i686-pc-mingw32-g++ (GCC) 4.7.3 i686-pc-mingw32-gcc (GCC) 4.7.3 i686-pc-mingw32-gcc-4.7.3 (GCC) 4.7.3 GNU Fortran (GCC) 4.7.3 i686-w64-mingw32-c++ (GCC) 4.8.2 i686-w64-mingw32-cpp (GCC) 4.8.2 i686-w64-mingw32-g++ (GCC) 4.8.2 i686-w64-mingw32-gcc (GCC) 4.8.2 i686-w64-mingw32-gcc-4.8.2 (GCC) 4.8.2 GNU Fortran (GCC) 4.8.2 x86_64-pc-cygwin-c++ (GCC) 4.8.3 x86_64-pc-cygwin-g++ (GCC) 4.8.3 x86_64-pc-cygwin-gcc (GCC) 4.8.3 x86_64-pc-cygwin-gcc-4.8.3 (GCC) 4.8.3 GNU Fortran (GCC) 4.8.3 x86_64-w64-mingw32-c++ (GCC) 4.8.2 x86_64-w64-mingw32-cpp (GCC) 4.8.2 x86_64-w64-mingw32-g++ (GCC) 4.8.2 x86_64-w64-mingw32-gcc (GCC) 4.8.2 x86_64-w64-mingw32-gcc-4.8.2 (GCC) 4.8.2 GNU Fortran (GCC) 4.8.2 -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
