"Now, some people (and I feel this group is growing) are going a step too far, by enabling -Werror __unconditionally__ in their software packages. And what applies to me - not being able to anticipate warnings in other compilers - of course applies to them as well"

"squid requires me to __doctor around in its configure__ script, and even __patch some Makefiles__, while qemu-linaro has a central location for it."

The complaint boils down to "-Werror is a development tool, so use it like that".
