Hi.
This is a missing piece of the libc_has_fast_function hook.
I'm going to install that as obvious as it breaks current trunk

Hi,
at the moment the alias stats outputs mostly 0 for res_may_alias_p

I think this is because of code refactoring where we added more variants
of this function and we want to do stats around the main worker.

Hi,
After Martin's commit r271338, we now emit quotes around reserved

This should fix them, OK?
Thanks! There will probably be a few more like this on other
targets. Jeff has been running a

Yes. it is. This is somewhat similar to strict-a

This patch fixes a naked inform call that can be seen with -w.
While at it, I added missing quotes; I'm surprisesd this wasn't fixed by the
recent patch Martin submitted.

When we have

"int()" is resolved to a type-id, as per [temp.arg]/2, causing this program to
fail to compile. This can be rather confusing so I think we want to improve the
diagnostic a bit.

This test fails in C++2a since r271338, because the types in the "aka" differ:
in C++17 and below we print:
{aka 'const char [3]'}
while in C++2a:
{aka 'const char8_t [3]'}
We can make the regexp accept both.
