There are ABI changes to the C++ runtime in GCC5. Do we want a new
constant here? Apparently there is some backward compatibility suport
this time:
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html
Yeah.. this raises some questions about usage of this header for the
buildhost
target (local machine running the build) vs the haiku target (haiku abi)
I wonder if these checks should be wrapped in __HAIKU__ to pick up on
buildhost vs haiku targets?
I'm guessing things like the filesystem tools that the buildhost
compiles
and runs are at fault here.
