Just for the record:
I just played with the script provided in stackoverflow which generates a
bat file, and it seems that the behaviour of the '-P' switch of setup  has
changed because now it explicitely needs the version of the package (at
least for me it didn't worked without the version number:  " -P
package=version_as_seen_by_cygcheck") . Can someone (probably Jon Turney)
confirm this usage of the '-P' switch (BTW the mandatory '='  is explained
nowhere - Nor in 'setup -h' or the setup web pages - and can be seen only
in  the source code).
By needing the version number the script on stackoverflow will then
generate a "too long" command in the bat file and it will crash; I had to
modify it manually to split the command line in 4 ...
Note on the script: if you forgot to run it before loosing your cygwin
tree, it can still work after a 'Base' installation if you kept the old
installed.db file and replace (temporary) the actual installed.db with this
one :)

Cheers,
