   4 Subject: [PATCH 1/1] Do not include sigcontext.h and asm/sigcontext.h (these
   5  Linux headers define sigcontext which is no longer used as replaced with
   6  ucontext_t in GC 7.0alpha1)
   7
   8 * os_dep.c: Do not include linux/version.h (do not test
   9 LINUX_VERSION_CODE), asm/signal.h, sigcontext.h, asm/sigcontext.h
  10 since struct sigcontext not used in GC v7+.
