Hm, I'm not exactly sure what you mean -- if you give -Werror to the compiler, 
then shouldn't you expect the compiler to stop when it encounters an 
error? If your Makefiles are written such that they don't show the actual 
commmand line of the compiler invokation, this can hardly count as a bug 
in gcc. 
 
That being said, we indeed have a regression: 
---------- 
main () {} 
---------- 
yields 
 
g/x> /home/bangerth/bin/gcc-2.95.3/bin/c++ x.cc -Wall -W -Werror 
cc1plus: warnings being treated as errors 
x.cc:1: warning: ANSI C++ forbids declaration `main' with no type 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ x.cc -Wall -W -Werror 
cc1plus: warnings being treated as errors 
x.cc:1: warning: ISO C++ forbids declaration of `main' with no type 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ x.cc -Wall -W -Werror 
x.cc:1: warning: ISO C++ forbids declaration of `main' with no type 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ x.cc -Wall -W -Werror 
x.cc:1: warning: ISO C++ forbids declaration of `main' with no type 
 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ x.cc -Wall -W -Werror 
x.cc:1: warning: ISO C++ forbids declaration of `main' with no type 
 
In other words, the indication of -Werror was dropped sometime between 
3.2.x and 3.3.x.
