And I see that --enable-gcc-warnings doesn't just enable warnings, but
makes them into errors:

make[1]: Entering directory `/home/larsi/src/emacs/trunk/src'
  GEN      globals.h
  CC       vm-limit.o
vm-limit.c:58:0: error: macro "__MALLOC_HOOK_VOLATILE" is not used 
cc1: all warnings being treated as errors
make[1]: *** [vm-limit.o] Error 1
make[1]: Leaving directory `/home/larsi/src/emacs/trunk/src'
make: *** [src] Error 2

(This is on an older Debian machine.)

I still think that warnings should be enabled by default (on Linux), but
they shouldn't be treated as errors.
