Prepare for coding sprint

Assumed:

• the usual build chain (gcc/clang, autotools, libtoolize, make/gmake etc)
• git
• editor, diff

Necessary (!):

• master and SW git check-outs and builds (native, in parallel) Additional (for SW-related git repository):
• own SW forks for pushing & sending pull requests
• added TC remote repository for testing

Helpful(?):

• git GUI, e,g. qgit, sourcetree, tig etc.
• sdiff (belongs to diffutils)

Extra:

• 32-bit build (for 64 native OS/builds)

what else???....
