Kevin Tucker <kevin-tucker at cox dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kevin-tucker at cox dot net --- Comment #1 from Kevin Tucker <kevin-tucker at cox dot net> --- Tried example on 5.3.0 on Cygwin and got reported results. Found similar results for unused variable warnings with following source: int main() { int i; return 0; } Compiled with: gcc -w -Werror=unused-variable -Wunused-variable unused.cpp Gives no error Also tried w/v6.0 (updated and built from r234482 of svn://gcc.gnu.org/svn/gcc/trunk) and got same results. However, I would think that if "-w" is given, then there are no warnings to promote to errors, since warnings are disabled.
