Sure?  Have a look into the rebaseall script:

  DefaultSuffixes='dll|so|oct'
  [...]
  Suffixes="${DefaultSuffixes}"
  [...]
  case $Platform in
    cygwin)
      find /etc/setup -name '*.lst.gz' | xargs gzip -d -c |
	grep -E "\.($Suffixes)\$" |
	sed -e '/cygwin1\.dll$/d' -e '/cyglsa.*\.dll$/d' \
	    -e '/sys-root\/mingw/d' -e 's/^/\//' \
	    -e '/d?ash\.exe$/d' -e '/rebase\.exe$/d' >"${TmpFile}"
      ;;

I don't see how it should be able to pick up a file with the suffix .osc.

You were using a not quite up-to-date mirror.  THis should be fixed
in the meantime.

_autorebase has a setup.hint file which results in adding itself to
the dependencies for all packages which come with files having the
suffix .dll, .sl, and .oct.  The problem was that the "upset" script
creating the setup.ini file only checks dependencies for newly uploaded
or update packages.  So at first, _autorebase was only added as a
dependency to the only updated package python-crypto.  But when we
realized it, cgf started the upset script from scratch, which is quite
a job and takes a couple of hours.  When I looked yesterday morning
(CEST), lots of dependencies to _autorebase have been added to setup.ini.

But, hmm, looks like there are still dependencies missing.  I don't see 
dependencies to _autorebase in a lot of "lib" packages, like libgcc1,
or libopenssl100.

Feel free to participate in further development of the rebase tool.
Patches for useful functionality is always welcome.  The right forum is
the cygwin-apps list.
