I'm just going to change isnanl to handle the invalid bit patterns
because I'm sick of this issue...

Fixed in git on Jun 8.

This test must be doing something wrong. musl's printf does not use
any dynamic memory.

I'll look into this. Locales are not presently supported, but the
interfaces are intended to work and behave as they should for an
implementation that has exactly one possible locale.

I'll look into it.

Odd, this is just a syscall wrapper, no?

I'm not sure if it's related, but musl defines PATH_MAX and does not
attempt to support explicit pathnames longer than PATH_MAX. I'll have
to look at what the test is doing.

This was a bug I reported to gnulib. The test is checking for GNU
semantics which are incompatible with POSIX, i.e. the test is
misnamed.

I think gnulib just wants GNU glob functionality. This is legitimate
for it to replace since we (at present, at least) don't attempt to
offer any GNU functionality in glob.

These conversions are definitely supported. The only related thing we
don't support is BOMs and stateful/endian-detected UTF-16/32.

I need to check this. I've suspected it might have a bug.

Odd, it uses strerror..

Sounds like a bug; I'll check it out.

This is a check for the GNU regex interfaces as opposed to POSIX
regcomp/regexec.

This was caused by a missing negative zero case for "-0x" followed by
non-hex chars. It's fixed in git.

OK, looking...
