Patches to add multiple include guards to all of GCC's internal
headers have been submitted in the past, but never approved and
applied, probably because they'd need an OK from someone with global
write privileges and all those people were too busy to review the
patch.

It was agreed, last time this came up, that in principle they should
all have guards.
