#==============================================
# Finally:
# check if we need to actually update something:
# version "11" added separate config files for gcc toolchains:
# version "12" version-specific specs files for gcc compilers:
# version "13" version- and architecture-specific specs files for gcc compilers:
# version "14" fixes a bug in previous ones; "-A" was not relayed to gcc config
# version "15" just forces a reconfiguration (to check that the "specs" file is
# used, due to a bug in the top-level Makefile of scratchbox2)
# version "16" added "host-ld_library_path.conf"; technically, we
# don't have to reconfigure gcc when moving from 15 to 16,
# but it is easier to just do everything..
# version "17" added a separate tool for configuring DEB_* variables
# and gcc configuration sets SBOX_GCC_TARGET even if
# -A option was given to sb2-init
# version "18" added cross_gcc_progs_path to gcc configuration
# version "19": changed detection of -Wno-poison-system-directories (gcc config)
# version "20": A bug has been fixed in gcc configuration.
