- add a framework to easily add new ones - add gdb as a first debug facility - add patches for gdb After the kernel checked its installed headers, clean up the mess of .checked.* files. Reorder scripts/crosstool.sh: - dump the configuration early - renice early - get info about build system early, when setting up the environment - when in cross or native, the host tools are those of the build system, and only in this case - elapsed time calculations moved to scripts/functions Remove handling of the color: it's gone once and for all. Update tools/addToolVersion.sh: - handle debug facilities - commonalise some code - remove dead tools (cygwin, tcc) Point to my address for bug reports.
