"Pascal" refers to a way of different way of pushing things onto the 
stack when calling things; there's "Pascal order" and "c order" when you 
call a function, each approach has its good and bad sides.  There's work 
in progress to support different calling conventions including Pascal 
order for LLVM at 
http://nondot.org/sabre/LLVMNotes/CustomCallingConventions.txt .  At 
this point, supporting different call conventions is supported in LLVM 
1.5:  http://llvm.org/releases/1.5/docs/LangRef.html#callingconv but it 
doesn't look like the syntax to support the Pascal one has made it in 
there yet.  Probably requires a fairly small patch to LLVM now that the 
main infrastructure is available.

Don't know if it's feasible to rip all the Pascal convention code out 
PostgreSQL, that's the other approach.
