A few more questions, if I may:

  . Is it true that time_r.c is needed only by mktime.c?  If so, the
    MinGW build of Emacs would not need to worry about time_r.c, since
    it wasn't compiling in mktime.c before the gnulib sync -- is that
    right?

  . Is it true that stddef.in.h, unistd.in.h, and time.in.h are needed
    only on systems which have "issues" with the corresponding
    standard headers?  If so, is it okay to compile gnulib sources in
    lib/ without editing these 3 into the corresponding *.h files?

TIA
