I read this as "While there have been C compilers for some time now  
that support the midrange PICS, there are certain constructs that are  
common in some application areas (eg ISO61131) that were NOT easily  
implemented by those C compilers that are much more easily implemented  
using the enhanced midrange architecture."

(I'm not sure how how function pointers were handled before, but it  
sure looks like it's a lot easier to do now!  For that matter, while  
it may not be a big deal to ASM programmers, the whole "registers,  
SFRs, RAM, and Flash now share a single address space" is probably  
REALLY nice for C compiler writers...)

(It's a nice sign that the compiler vendors were involved with this so  
early on in the games...)
