RAM usage of applications?

[egarrulo]

Hello everybody,

I wonder if I could consider Chicken to write an application for a 
device with 256 MB of RAM, where the whole RAM may not be available for 
the application.

Can anybody give me a *rough* idea of how much RAM a basic program 
written in Chicken and transpiled to C could require at run-time?  Some 
megabytes, dozens of megabytes, etc.  With all features enabled, if 
feasible.  Speed is not a concern.

Thank you.
