The fix is already included in gcc 7.2 release [1]. We have to backport it to
all older gcc release since it's not included in any stable release yet.

Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
|
|
|
|
Current glibc no longer gives the ucontext_t type the tag struct
|
|
ucontext, to conform with POSIX namespace rules. This requires
|
|
various linux-unwind.h files in libgcc, that were previously using
|
|
struct ucontext, to be fixed to use ucontext_t instead. This is
|
|
similar to the removal of the struct siginfo tag from siginfo_t some
|
|
years ago.
|
|
|
|
This patch changes those files to use ucontext_t instead. As the
|
|
standard name that should be unconditionally safe, so this is not
|
|
restricted to architectures supported by glibc, or conditioned on the
|
|
glibc version.
|
|
|
|
Tested compilation together with current glibc with glibc's
|
|
build-many-glibcs.py.
