- make creating uconfig.sh automatic (by pumpkin)

- make creating Makefile.micro automatic (by pumpkin)

- clean up compilation warnings as much as possible:
  most of them seem to stem from not including enough headers (as planned)
  to have enough prototypes, these may be correctible with some simple casts

- do away with signals? (not very portable outside UNIX lands)
  (missing signal API prototypes cause the majority of the compilation
   warnings anyway) 

- do away with fork/exec/wait? (system, popen should be enough?)

- some of the uconfig.sh really needs to be probed (using cc) in buildtime:
  (uConfigure? :-) native datatype widths and endianness come to mind
