added warnings for useless variables (at verbose level 1)
- exact definition of 'useless' may be further refined
- display could certainly be improved

- simplification of clock calculus (may be still buggy, work in progress)
no impact on unclocked programs.

- some minor adjustments...

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@228 041b043f-8d7c-46b2-b46e-ef0dd855326e

- reimplemented computation of dead variables
- added computation of a reuse policy (depending on types)
- not yet used though, would have to change code generation
in order to be useful...

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@216 041b043f-8d7c-46b2-b46e-ef0dd855326e

- work in progress for stateless/stateful status computation
(to turn conditionals into merges, which yield more efficient C code)

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@198 041b043f-8d7c-46b2-b46e-ef0dd855326e

- added struct types declaration
- added constant definition with a struct type
- added checking for multiple definitions of nodes (behavior was buggy)
- better and more uniform error messages
for undefined/already defined symbols

We still need struct expressions......

more steps towards struct types...
