can you elaborate on MachineDesc and how to construct one for the local machine?

Hi,
(cc-ing list)
thanks, glad you like it. MachineDesc specifies the size (in bytes)  
and alignment requirement (in bytes) on a certain architecture. I'm  
not too familiar with the internals (implemented by Aaron Tomb), but  
have a look at the machine description for i386 in src/Language/C/ 
Analysis/AstAnalysis.hs, and how it is used in src/Language/C/Analysis/ 
ConstEval.hs.
cheers, benedikt
