Yes, that sounds right.

I'm not sure it's worth the effort. Bison doesn't require full support 
for C99, and it would be a maintenance burden to document the exact set 
of C99 features it needs, a burden that would fall both on Bison 
maintainers (who would have to maintain a list of features that almost 
nobody cares about) and on Bison builders (who would have to read that 
list and assume it's important and run through the checklist, even 
though the list would be a waste of time for almost all of them).

I wouldn't even add info about which VS version is needed, since that 
will likely evolve too. At most I would add a brief note to the FAQ that 
is easy to maintain as it avoids mentioning specific versions. I 
installed the attached as an attempt to do that.
