[Libunwind-devel] [Patch] Fix empty structs in libunwind-x86_64.h

[Лежанкин Иван]

Hi,

there is a compilation issue with Clang and latest libunwind - It's
about "typedef struct unw_tdep_save_loc" and one more struct:

include/libunwind-x86_64.h:111:9: error: empty struct has size 0 in C,
size 1 in C++ [-Werror,-Wextern-c-compat]

The solution is very simple:

diff --git a/include/libunwind-x86_64.h b/include/libunwind-x86_64.h
index 526b1ea..99f7210 100644
