The other thing is before this change, the C++ front-end was inconstaint with the preprocessor and now it is constaint. So adding -pedantic-errors made those warnings into errors while doing -pedantic-errors -fpermissive will still kept them as errors. As shown by: [EMAIL PROTECTED]:~$ ~/x86-linux-4.0.2/bin/gcc t.cc -pedantic-errors -fpermissive t.cc:2:1: error: "a" redefined t.cc:1:1: error: this is the location of the previous definition [EMAIL PROTECTED]:~$ ~/x86-linux-4.0.2/bin/gcc t.cc t.cc:2:1: warning: "a" redefined t.cc:1:1: warning: this is the location of the previous definition /usr/lib/crt1.o(.text+0x18): In function `_start': ../sysdeps/i386/elf/start.S:98: undefined reference to `main' collect2: ld returned 1 exit status Thanks, Andrew Pinski
