This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
Mostly non-ANSI function declarations, using 0 as NULL and inline
function prototypes. Also removed unused S_HTTP_100 network state
enum type, which text message contained unknown escape sequence: '\?'.
Convert remaining conditional file building to use
OBJS-$(CONFIG_FOO) += foo.o
one problem with reverse meaining (in util/) fixed with local 'hack'.
Cleanup and remove stuff which is now default targets.
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
Finally, we are able to identify the builds more accurately. Now we check
if commit-id (cogito tool) is available and pass the output to vernum.c
compilation which then exports it as a build_id string.
The first line of --version is now a bit long, we should probably move the
build date to a second indented line or something.
