[Bug 276738] clang: static_assert conflicts with -std=c++98 -pedantic-errors

(In reply to Henri Menke from comment #2)

My notes on interpreting this:

"it doesn't say anywhere explicitly that C++98 is unsupported.":
listing everything not supported is highly unusual and would be
a big effort. Normally if support is not mentioned, it is not
supported and what is explicitly supported is explicitly mentioned.

The lack of a page https://libcxx.llvm.org/DesignDocs/ExtendedCXX98Support.html
is also highly suggestive of lack of C++98 support.

Even https://libcxx.llvm.org/DesignDocs/ExtendedCXX03Support.html says
for C++03:

QUOTE
Clang provides a large subset of C++11 in C++03 as an extension.
END QUOTE

(Again, an explicit mention of the partial support.)

But C++03 is after C++ 98 as well and that note does not imply
anythign for the C++98 status.

I fully agree that having a error report that was in terms of
static_assert notation would be far better error handling than
what now happens. But an error report of some kind should be
what happens as far as I can tell.

Being C++ backwards compatible is messier than for C generally.
It is unlikely FreeBSD would taken on such for C++ subjects where
upstream does not. Quality of error messages where FreeBSD code
contributes to why the message is odd is something FreeBSD is
more likely to deal with.
