Python is not able to detect if compiler double representation is
compliant with IEE754:
checking whether C doubles are little-endian IEEE 754 binary64... no
checking whether C doubles are big-endian IEEE 754 binary64... no
checking whether C doubles are ARM mixed-endian IEEE 754 binary64... no
Accordingly 'legacy' mode isused. It is possible to check this at
runtime by check if 'sys.float_repr_style' contains 'short' or
'legacy'. Calculus correctness is not garanteed with 'legacy'.
Problem is better described here:

However, all gcc architecture use a representation compliant with
IEE754. So, we can enable it unconditionnaly.
