Ok, I wasn't aware of this.

That makes sense, but OTOH, we want to avoid silly names I guess.  ;-)

So, do you think we should rename them to `strto{d,l}' or documenting
this dependence is enough?

I couldn't think of any other option that would retain consistency.

The mutex is statically initialized, how can it impact startup time?

More importantly: what's the semantics of a "misc" mutex?  Suppose
function `foo' invokes `bar', which in turn invokes `string-locale<?'.
What if both `foo' and `string-locale<?' turn out to lock the "misc"
mutex upon entry?

Hmm, I thought `unresolved' was for cases where a test cannot be run for
some reason.  See, e.g., `guardians.test', `socket.test'.  OTOH,
`unsupported' seems to be used when a feature cannot be tested because
it wasn't compiled in (e.g., `alist.test').  Well, there's admittedly
not a huge difference.

Thanks,
Ludovic.
