It does, thanks for the tip. I added this to my makefile:
check_gcc = $(shell if $(CC) $(1) -S -o /dev/null -xc /dev/null > /dev/null
2>&1; then echo "$(1)"; else echo "$(2)"; fi ;)
# Work-around for stupid gcc 4.2 bug
ifneq ($(findstring Werror,$(WARN)),)
WARN += $(call check_gcc,-Wno-error=cast-qual,)
endif
... now it compiles fine with -Werror both on gcc 4.1 and 4.2.
It would be nice if this bug would get somehow documented on gcc manual or the
main site before gcc 4.2.3 release.
