... related to __INT_MAX__ and friends not being defined, and various
__builtin.. function declarations missing (they should probably be added
to sparse, but I am lazy).
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: '\?'.
It is a little ugly since I couldn't get $(wildcard) to expand *.o files
so it just checks if there are any *.c files and then link in the lib.o
based on that.
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.
