Exponential function

There was a bug when using any quadmath expq function on GCC : GCC bug #60349 caused by mingw-64 bug #368.

To work round this defect, an alternative implementation of 128-bit exp was temporarily provided by boost/cstdfloat.hpp.

The mingw bug was fixed at 2014-03-12 and GCC 6.1.1 now works as expected.

[Tip] Tip

It is essential to link to the quadmath library
