pacman/lib/libalpm/alpm_list.h
Aaron Griffin 170d63190a * Shuffled some of the alpm_list free funtions - still not perfect, but better
* Added alpm_list_remove_node for single list node removal
* Proper error checking/output for failed db_read/db_write (missing files)
* Invalid packages (missing files) are now removed from the package cache
* -Qs and -Ss output now look the same
* config.rpath causes errors on one machine I had, so I added it to CVS
* Fixed a "clobbered memory" issue when installing groups - only the outer list
  should be free'd, not the contained data
