IMO, he wasn't really serious about that "proposal" -- and even if it
were, he wanted /me/ to run point on it, not himself. It was more of a

won't solve the problem (for DESTDIR + mingw). We've (the mingw team)
always recommended that users configure using "--prefix=`cd /posix/path
&& pwd -W`" under MSYS, which results in "$(prefix)=C:/mount/point/path"
(I don't know what Keith uses for --prefix when configuring in his
customary cross-build environment). So, even if SYSDRIVE itself is
accommodated, you'd have to *rewrite* $prefix behind the user's back,
removing its X: component if present. Plus, if $DESTDIR also contains a
sysdrive, which one do you use? Either choice will cause problems...
No way that sort of thing would fly with the auto* teams, and I reckon
Keith knows that. Hence, not a serious proposal.
IMO, his real goal is to "encourage" (force) everyone to stop using
DESTDIR altogether. I admit, he has a point: the FSF only requires that
'make install prefix=/new/prefix' work; they impose no such requirement
concerning DESTDIR -- probably because it just doesn't work on some
platforms like mingw. But I object to the 'leveraging' he's using here:
by refusing to allow DESTDIR in winsup/mingw, he makes it so that we
(cygwin) might as well expunge DESTDIR from winsup/*/ entirely --
because DESTDIR is useless from $(build)/i686-pc-cygwin/winsup.
But that's his unilateralism forcing /our/ decisions, and I object to
that, without a more grounded reason than, as Ralf put it, "when users
look at our (mingw's) makefiles, they might think it could work".
