Ok I will add somewhere here

just below the cmake truly cygwin packages....

in reality all this C99 started as I want to rid 
of the test failures of octave due to
incorrect handling of complex Inf .

-----------------------------------------------------------
>>>>> processing /pub/hg/octave/src/data.cc
  ***** assert(log2(complex(0,Inf)), Inf + log2(i));
!!!!! test failed
assert (log2 (complex (0, Inf)),Inf + log2 (i)) expected
Inf + 2.266i
but got
NaN + 2.266i
NaNs don't match
-----------------------------------------------------------

So it is a pure math aesthetic personal need.
But, I have not yet checked if it works.

 :-? 
Murphy go away
