[PD] help with error compiling externals in 6.externs?

Ooops... On my ubuntu partition, on another hand, although it too is a
recent upgrade, the lack of build-essential doesn't seem to be the problem,
neither does a lack of libc.so or libm.so.

What is going wrong on that partition looks like:
root at lapcritter:/usr/lib/puredata/doc/6.externs# make pd_linux
cc -DPD -O2 -funroll-loops -fomit-frame-pointer -Wall -W -Wshadow
-Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch
-I../../src -fPIC -o obj1.o -c obj1.c
obj1.c: In function ‘obj1_float’:
obj1.c:15:25: error: unused parameter ‘x’ [-Werror=unused-parameter]
 void obj1_float(t_obj1 *x, t_floatarg f)
                         ^
obj1.c: In function ‘obj1_rats’:
obj1.c:21:24: error: unused parameter ‘x’ [-Werror=unused-parameter]
 void obj1_rats(t_obj1 *x)
                        ^
cc1: all warnings being treated as errors
makefile:58: recipe for target 'obj1.l_ia64' failed
make: *** [obj1.l_ia64] Error 1

(?)
