Comment (by ballapete):

 I think `libff @3.4.6` works fine! I "played" a bit with make/gmake in
 `testsuite/libffi.bhaible`, built the two test programmes and ran them
 manually. The results, the failures, are these:

 {{{
 pete 278 /\ cat failed-call
 Float f(Float,float,double):({0.1},0.2,0.3)->{0.6}
 Float f(Float,float,double):({0.2},0.3,-9.80879e-154)->{0.5}
 Double f(float,Double,double):(0.1,{0.2},0.3)->{0.6}
 Double f(float,Double,double):(0.1,{0.3},-9.80879e-154)->{0.4}
 Double f(Double,float,double):({0.1},0.2,0.3)->{0.6}
 Double f(Double,float,double):({0.2},0.3,-9.80879e-154)->{0.5}
 pete 279 /\ cat failed-callback
 Float f(Float,float,double):({0.1},0.2,0.3)->{0.6}
 Float f(Float,float,double):({-1.99908},0.1,0.2)->{-1.69908}
 Double f(float,Double,double):(0.1,{0.2},0.3)->{0.6}
 Double f(float,Double,double):(0.1,{6.52217e-310},0.2)->{0.3}
 Double f(Double,float,double):({0.1},0.2,0.3)->{0.6}
 Double f(Double,float,double):({-1.99264},0.1,0.2)->{-1.69264}
 }}}

 I think this can be expected. The `PowerPC G4 CPU` is only 32 bit.
 Possibly this physical limitation produces the failures. Using a different
 math library might resolve the issues…
