[Liberty-eiffel] Minimum forking support

[Paolo Redaelli]

Hi Raphael,

I've been reviewing the status of wrappers and I think that I should commit this diff to provide a really minimal support to forking and waiting.

It's really really simplicistic, the bare minimum to justify the existence of the "posix" wrappers which I should obviously improve to release curtis.

I tested the forking exampple on two installation:

• on my developing machine with "rolling" version of compiler
• on my cloud server with rc1

They both compile and run as expected. I've checked (with src/wrappers/scripts/check-cluster.sh which uses class_check) that no syntax error is introduced but as we are in RC I think it's wise with someone else also checks they run on his/her machines.

If it is the case I'll commit it.

Happy hacking

 Paolo
