4 - optimize slightly bound checking when doing addition + dereference.
5 - better section generator (suppress some mmaps).
6 - To check: bound checking and float/long long/struct copy code
7 - To check: 'sizeof' may not work if too complex expression is given.
8 - fix bound check code with '&' on local variables (currently done
9 only for local arrays).
13 - add PowerPC or ARM code generator and improve codegen for RISC (need
14 to suppress VT_LOCAL and use a base register instead).
15 - interactive mode / integrated debugger
16 - fix multiple compound literals inits in blocks (ISOC99 normative
17 example - only relevant when using gotos! -> must add boolean
18 variable to tell if compound literal was already initialized).
19 - add more bounds checked functions (strcpy, ...)
20 - fix L"\x1234" wide string case (need to store them as utf8 ?)
21 - fix preprocessor symbol redefinition
22 - better constant opt (&&, ||, ?:)
23 - add ELF executable and shared library output option (would be needed
25 - D option with all #define cases (needs C parser)
26 - add portable byte code generator and interpreter for other
27 unsupported architectures.
