# Due a mutual build-time dependency between libc++abi and libc++, it is
# preferable that we build them within the same APKBUILD to avoid duplication.
# Since nothing else seems to need libc++abi and we need to compile it into
# libc++ statically anyway to make -static with libc++ work, we don't actually
# create libc++abi packages. If something arises that depends on libc++abi,
# this may change, but for now this is the simplest approach.

musl doesn't support strtoll_l(), so replace it with a simple strtoll() call.

libc++'s stddef.h uses non-standard macros to detect if max_align_t exists,
which break on musl. We reluctantly add musl's non-public macro the list
for now, but this should be fixed more fundamentally.

musl doesn't support the locale things that the locale requirements test, like
localized money and decimal formatting.
The syscat.errcat tests are broken and rely on the libc to return a specific
string in the form of "Unknown error <n>" for unknown errnos when calling
strerror(), which is not defined anywhere and libcs are free to return any
string they want, up to and including "libcxx tests are silly".
Similarly to glibc, musl uses "NaN" to format NaN long doubles, not "nan".
Finally, musl uses "0" to indicate a NULL pointer as %p argument to *printf().

Shiz created this revision.
Herald added a subscriber: mgorny.
As per r241993, libunwind_ext.h is not used anymore, and thus only the public libunwind includes are needed.
This eases distro packaging efforts and removes an unneeded requirement for out-of-tree building.
