When building with "... -g0 -DNDEBUG -Wall -Wextra -Wpedantic" then the
following error happens:
../../../gcc_trunk/libatomic/config/posix/lock.c: At top level:
../../../gcc_trunk/libatomic/config/posix/lock.c:58:3: warning: missing
initializer for field 'pad' of 'struct lock' [-Wmissing-field-initializers]
[0 ... NLOCKS-1].mutex = PTHREAD_MUTEX_INITIALIZER
^
The folowing patch fixes it.
Regtested x86_64-linux.
NOT committed b/c don't have write access yet.
