ldd did not complain, but your question reminded me that I should try 
running under strace. That produce the complaint:

    The procedure entry point
    _ZNSt19basic_ostringstreamlcSt11char_traitslcESalcEEC1Ev could not
    be located in the dynamic link library C:\cygwin64\bin\cmake.exe

(I had to type that in, as I could not copy from strace's error dialog.)

That looks like it might be an issue with the g++ library? Any chance 
there was a change in the library that might require a recompile/relink?

I will try rolling that one back.
