You shoot yourself in the foot by using --with-cc-opt="... -Wall
....". This results in:

I.e. warning options set by nginx (notably "-Wall ...
-Wno-unused-parameter") are overriden by your "-Wall" which comes
later, and this results in compilation failure due to "-Werror"
also set by nginx.

Not passing "-Wall" by hand will fix this while still ensure that
warnings unexpected in the nginx source code will be fatal.
