Tables: less executable code -> less maintenance and bugs, if one entry
works, all work.

#defines: using #define for constants is reducing the C compiler to a
super-assembler. If someone likes to program assembler, one should
actually use the assembler and not misuse cpp for that purpose. C does
have a notion of types (although not strongly enforced -- a shame) and
using #defines you're totally defeating any sense of types. Also, if
used heavily, the code is really difficult to debug, gcc -E output is
not pretty.
