OK, attached are proposed patches to emacs-28 to merge Gnulib into the 
emacs-28 branch. This is intended to be what I posted to Bug#33847 in 
July, except taking more-recent Emacs and Gnulib changes into account. 
Although the 1st patch is large, it's almost all automatically-generated 
by admin/merge-gnulib. I haven't tested the 2nd patch, as it's 
Microsoft-specific and I am mostly just guessing about Microsoft.

As you can see from recent activity in the emacs-28 branch I have also 
fixed a few glitches that prevent Emacs from building on Fedora 34 if 
configured with --enable-gcc-warnings, or from building on draft C2x 
platforms; those fixes are small and are independent of the attached 
patches. The attached patches fix several more glitches of this sort. A 
few such glitches still remain; I plan to look into those after this 
patchset is installed.
