Comment:

 One option is to use TLS, e.g.
 {{{
 diff --git a/gcc/ada/gcc-interface/Makefile.in b/gcc/ada/gcc-
 interface/Makefile.in
 index 598b262d914..5e1c5286d63 100644
 --- a/gcc/ada/gcc-interface/Makefile.in
 +++ b/gcc/ada/gcc-interface/Makefile.in

 }}}
 Another option is to use POSIX keys:
 {{{

  endif
 }}}
 I tend to use TLS since it has less overhead.
