--- Comment #5 from Richard PALO <richard at netbsd dot org> ---
kind reminder to push these two patches:
1) https://gcc.gnu.org/bugzilla/attachment.cgi?id=33031
2) and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61649#c1 (*)
* NB https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52168

I believe I already answered Jonathan's question in that since
only a [preceeding] line of context is being added, there is no
additional '#endif' to add.

BTW, this line of context is necessary anyway, because if either
Oracle Solaris or Illumos change this code section, for example by 
fixing it as gcc currently does here, it will prevent fixincl.x from
action which would actually *break* the file.
