-Subject: [PATCH 15/15] Force linking to libgcc_s_dw2-1.dll [deprecated]
-
-.. by adding to specs:
-*libgcc
---undefined=___deregister_frame_info
---undefined=___register_frame_info
-
-These flags get added twice to the ld command line
-because of %G appearing twice in:
-*link_gcc_c_sequence
-%G %L %G
-so this should be tidied up really.
-
-20150805 update:
-
-Looking at this again, it seems that the
-SHARED_LIBGCC_UNDEFS_SPEC stuff added in commit 7d804f
-does the same thing, so my hack may not be needed. It
-would appear that for some time, DWARF2_UNWIND_INFO
-was not defined, but it's OK now. Latest specs have:
-*shared_libgcc_undefs:
-%{shared-libgcc: -u ___register_frame_info -u ___deregister_frame_info}
