Comment (by Tony Reix <tony.reix@…>):

 Replying to [comment:4 johnmaddock]:

 I've the result for the previous change
 (BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS): I now have MUCH less errors.
 However, I simply did a quick rebuild/retest from existing state and not a
 complete rebuilt/retest after a full clean . Anyway, I now see that this
 long double issue is the root cause for MANY of the errors I've seen.

 About your second suggestion, I've removed the previous change (NO "long
 double") and added a defined(__PPC__) at beginning of the #if . However, I
 have yet no idea about how long is the mantissa... I've asked for some
 paper summarizing the choices made for Linux on PPC64 (because they are
 different from the ones made for AIX).

 About github, I'm no more familiar, but I have a colleague who knows it
 very well and should be able to refresh/update my memory.

 Last: are there some Boost documentation explaining the main files used by
 Boost for its basic configuration, like boost/math/tools/config.hpp ?

 Thanks/Merci

 Tony
