 Replying to [comment:2 johnmaddock]:

 Thanks for your comments ! [[BR]]
 I'm now recompiling/testing Boost with such a change:

 # g++ -E -dM boost/math/tools/config.hpp | grep LONG_DOUBLE [[BR]]
 #define _GLIBCXX_LONG_DOUBLE_COMPAT 1 [[BR]]
 #define __SIZEOF_LONG_DOUBLE__ 16 [[BR]]
 #define BOOST_MATH_NO_NATIVE_LONG_DOUBLE_FP_CLASSIFY [[BR]]
 '''#define BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS''' [[BR]]
 #define __LONG_DOUBLE_128__ 1 [[BR]]
 #define __LONG_DOUBLE_MATH_OPTIONAL 1 [[BR]]

 I should have the answer in some hours.

 About your suggestion to provide me with some ideas on how to support
 "double double", I'm OK to work with you. I may spend days and maybe some
 weeks on this. I have access to both PPC64 BIG/LITTLE Endian machines,
 installed either with Ubuntu or Fedora (for now). [[BR]]
 I'm new to Boost. [[BR]]
 Just let me know your suggestions, plus some explanations and pages to
 read, and I'll experiment them.

 :)
