Not good for users that are unfamiliar with cygwin, uninterested in cygwin
itself or something else on that "line".

Heh... that would IMO require setup.exe to be able to do batch runs. Not
possible, unless changes has been done very recently.

I'm not keen of seeing this kinds of solutions being run on my computer as
it is "low spec" to put it mildly.
First of all; The "FindFirstFile()/FindNextFile()" thingie would probably
run for ten minutes, or even more. I would be sitting there wondering what
the heck was happening, and I would *not* be polite to the person who
created this misnomer.
Second; how is this "FindFirstFile()/FindNextFile()" thing supposed to
handle the existense of more than one device? i.e:
$ mount | grep -re '^.: .*'
P: on /dev/dvd type system (binmode)
Q: on /dev/zip type system (binmode)
R: on /dev/dcdr type system (binmode)
S: on /dev/dcds type system (binmode)
T: on /dev/dcdt type system (binmode)
U: on /dev/dcdu type system (binmode)
c: on /cygdrive/c type system (binmode,noumount)
d: on /cygdrive/d type system (binmode,noumount)
e: on /cygdrive/e type system (binmode,noumount)
f: on /cygdrive/f type system (binmode,noumount)
g: on /cygdrive/g type system (binmode,noumount)
h: on /cygdrive/h type system (binmode,noumount)
i: on /cygdrive/i type system (binmode,noumount)
w: on /cygdrive/w type system (binmode,noumount)
is what I have available currently. Is that thing supposed to look through
all of it? If I connect my Digicams there will be three more devices to scan
through. What if it finds more than one cygwin1.dll, is it supposed to erase
the second one then?
Please, don't even mention this anymore, that's real bad programming IMO.
Not very likely to end up in something viable.
There got to be better, future-safe, flexible and extendable aproaches to
this. A good *attempt* at this was presented above IMO.
