Hello Dimitry and thanks for your answer.
I am pretty sure it does indeed support long double. It's configured with
vfpv3-d16 - but I noticed that c++config.h in gcc has _GLIBCXX__HAS_FABSL
and friends are undefined. I think I need to look deeper at the
configuration of our toolchain.
long double support is required in libc++ then I gather?
