No - it's not right with my setup - where I have C:\ mounted as /C.
With Cygwin 1.5 (which has exactly the same bash.sh) I get
DEVDIR=/C/c:/cygwin/dev, and with 1.7 I get /C/C:/cygwin1.7/dev.
Interestingly, the 1.7 install seems to have detected my 1.5
mount points and preserved them - I wasn't expecting that.
I guess this must have been broken on 1.5 for ages, but did no harm
as the create would fail as ":" was invalid in filenames.

Would it have been a workaround for buggy cygpath or setup.exe in
the past?

Quite.
