Yes, for now, but once I add the strftime module, time_r.c will also be needed
by strftime.c, and in that case MinGW will definitely need to worry about

strftime is quite likely to be added.  I've already coded it up and tested
it, and it works fine on POSIXy platforms.  I plan to add it to Emacs
soon.  Once it's in, Emacs's format-time-string function can start supporting
higher-resolution time stamps.

The "issues" are either with the headers, or with the implementations of
functions declared by the headers.

If the MinGW headers and implementations are good enough, you should
be OK without the .h files.  I'd be surprised if that were true, though.
