Yeah. That thought occurred to me as well. However there are
no libs in the windirs of the pattern "cyg*.dll". Those _should_ be
the key libs, though let me check for any other possible dups...

log="$(echo $d|sed -r 's!/(...)[^/]*!\1!g')dll.txt"
'ls' -1 "$d"/*.dll >$log
done
/tmp> wc -l *dll.txt
230 bindll.txt
6 windll.txt
1624 winsysdll.txt
1860 total
/tmp> cat *dll.txt|tee rawconcat.lst|sort|tee sorted_concat.lst|\
uniq -d >zdups.lst; wc -l *.lst|grep lst
1860 rawconcat.lst
1860 sorted_concat.lst
0 zdups.lst

It doesn't appear that there should be any conflicts...unless I messed
something else up...

(reading ahead)...so MS is back to their old *illegal* tricks?
Wasn't them using "private" or "hidden" interfaces in the OS to make
their products run better one of the reasons for the monopoly suit -- or
an unfair trade-practice type suit?
If they really only permit their version of a "POSIX" subsystem
to use certain WinNT calls, it would seem that's using their monopoly
power to exclude or degrade functionality in cygwin. IANAL (but I've
been exposed to a few and seen them on TV! :-)), but that practice would
seem to be of questionable legality.
Maybe while MS is "feeling in the mood" (forced by EU decisions) to
release specs of internals, someone (of properly, appropriate legal
'scariness') could nudge them on this if it would be useful to the cygwin?
I wonder -- haven't tested it, but wonder if their posix
implementation handles allowing the removal of open files properly.
They could "do it under the covers"...any attempt to delete an open
file or write to an open file would silently move the locked file
to some 'temporary name' and mark it "delete-on-close" -- or at
worst, add it to the "pending delete&rename registry key" to be
deleted at next boot.
