2. The commentary to the right of "#else" and "#endif" used to
be stripped. I put it inside "/* */".
Trying to modify what fixincludes does is always a risky business.
What if this commentary includes a comment? If you have
#endif foo /* stuff */
you then get nested comments and we still get a warning with -pedantic.
Looking through the ChangeLogs, I see that we did indeed run into a problem
with this, though it is not the first case I thought of. Consider this
example
/* Comment out this stuff
#ifdef foo
...
#endif foo
end of comment. */
If you fix the foo by changing it to /* foo */, then you now have a nested
comment. This is worse than what we started with, because this is now a
syntax error regardless of what options are used.

* fixinc.svr4: Remove everything after #endif, instead of trying
to turn it into comments, which loses inside comments.
* fixincludes: Likewise. Remove #endif workarounds for Ultrix 4.[12]
and SunOS 4.1, which are no longer needed because of this bug fix.
