Why would it be that hard? VAX C passed everything by value, while
Pascal let you specify descriptors, references, immediate value ... all
the options.

 
There ware decisions to be made, like what order do you push variables
onto the stack, when do you push the return address, how to interpret a
Pascal String in C.

All these things were standardized in the VAX/VMS ABI, right from the
beginning.
