Actually, generic vs gnu-linux locale crap is not the issue here. The
*ABI* support stuff in musl should make the gnu-linux code work on
musl if it was already compiled using glibc headers. It's the headers
that are incompatible with the gnu-linux os tree because we don't do
the ugly table-based stuff (which is much more bloated and probably
slower).
The issue that DOES matter with libstdc++ is name mangling. musl's
ABI-compat is limited to C. The type sizes and non-opaque type
representations match what's used on glibc/LSB, but the struct tags
and specific types for abstract opaque types like FILE and pthread_t
differ, meaning the name mangling will differ... Thus while you can in
theory use glibc-linked C++ programs with musl's LSB ABI support, you
can't mix-and-match glibc-linked C++ program/library code and
musl-linked C++ program/library code in a single program. The name
mangling will fail to match and the dynamic linker will fail to
resolve the C++ stuff.
