By default, the current setup.exe disables Cygwin permissions when
running postinstall scripts by adding nontsec to the CYGWIN environment
variable; that's why your file permissions are not being set in the
postinstall file. It also doesn't understand Cygwin permissions itself,
so it installs files from the tar.bz2 using Windows ACL semantics.

A workaround should be to set CYGWIN=3Dntsec inside the postinstall
script. I don't know if that takes immediate effect, but I do know (from
one of my own custom packages) that it works for scripts spawned from
the postinstall script, at least (i.e. run 'CYGWIN=3Dntsec mychownscript'
from your postinstall script).

As I understand it, newer versions of setup.exe (such as for Cygwin 1.7,
though there might be a snapshot of setup.exe for Cygwin 1.5 that has
these changes, too; I don't know) will install files using Cygwin
permissions, so such workaround will not be necessary when 1.7 is
released.
