If this patch can survive a few releases without complaint,

C99 existed).
Correct. MSVC also supports designated initializers but does not fully
support C99.
Out of curiosity, does MSVC define __STDC_VERSION__, and if so, to what?
It does not. While it does support a subset of C99's features, it
doesn't support the entirety of that language so defining
__STDC_VERSION__ would be inaccurate and misleading.
And obviously before releasing this or anything similar, it would be
nice to see results from people building pu. I'm especially curious
whether MSVC would work with this (or if people even still use it, since
Git for Windows is pretty mature?).
We do use MSVC internally as that gives us access to the great debuggers and
profilers on the Windows platform. Fortunately, this particular C99
construct _is_ supported by MSVC. I applied the patch below and complied it
with both MSVC and gcc for Windows and both builds succeeded.
Thanks. This kind of prompt testing and response is very appreciated. It
is unfortunate if we have to pick and choose C99-isms rather than using
the whole thing as a base. But that's probably just reality.
