try to execute daconfig/daconfig.exe or "type" them give:

cygcheck (note corrupted [split] quotes across a path element and inclusion
of quote chars in the path elements) gives:

If I remove the quotes from the system environment variable
in the control panel and reboot, all works:

Which is all correct.
Therefore, I think there is an incorrect interpretation (or conversion)
of quoted windows paths. For one thing, it appears to be using the colon
in "c:b" as a path separator instead of grouping it all together according
to the higher precidence quotes.
PS. I looked in the FAQ, thru the mailing lists (search words +quote +path
and +quoted +PATH, and didn't see anything).
PPS. I wrote a version of the "which" command, in which I did some really
minimal parsing of quoted windows paths, but it works correctly in the
cases above. I noticed this same problem in my program a while ago, (and
fixed it by adding the minimal quote parsing). Didn't think to check
cygwin's operation.
I can forward my "which" program to anyone who wants it.
