I'm glad it's now fixed.  But for the mingw-gcc-* packages, setup does
not actually create or delete any of those links, it is all done by
postinstall/preremove files.  If you take a look (see
/etc/{preremove,postinstall}/gcc-mingw*) you will see that the preremove
script only deletes the files contained in the manifest, and the
symlinks are not included there; and the postinstall only tries to
create the symlinks if they don't exist.  This could be considered a
slight packaging bug I suppose, since once created, those symlinks will
never be removed/recreated on reinstalls.
