[fpc-devel] Summer of code collaboration

[Vittorio Giovara]

Indeed, a fpc->js code generator would have a rather limited use. A
LLVM backend instead could be use on many more levels, and for example
could improve (or replace) the compilation process on iOS.
Plus I would like that this collaboration would be about something
that could be useful for many projects, not something hedgewars-only.
