Tested x86_64-linux, and verified with -fsigned-char -fshort-wchar
(which makes the underlying type of wchar_t be unsigned short).
Nightstrike also tested on mingw-w64.
Pushed to trunk.

For a port with signed char and unsigned wchar_t initializing a wchar_t
array with a char is a narro
And here is a second set of changes to bring config-list.mk largely in
line with the current situation on FreeBSD.
(It probably makes sense to switch to, or add, powerpc64le. I'll leave
that to others closer to that.)

Looks OK to me, thanks for the patch.
Committed with the idiomatic approach.
I'll work on this additional check later.

In the case of the CALL0 ABI, values that must be retained before and
after function calls are placed in the callee-saved registers (A12
through A15) and referenced later. However, it is often the case that
the save and the reference are each only once and a simple register-

The 64-bit variant of PMULL{2} and AES instructions are available if FEAT_AES
is implemented according to the Arm ARM [1]. Similarly FEAT_SHA1 and
FEAT_SHA256 enable the use of SHA1 and SHA256 instruction variants.
This patch fixes arm_neon.h to correctly reflect the feature availability based
