I have asked R. Stallman about this and the answer he gave is essentially
"Using and Porting GNU CC" V2.4 Sec. 14.18, where he states
"People frequently have the idea of using RTL stored as text in a file as
an interface between a language front end and the bulk of GNU CC. This
idea is not feasible."
He then goes on to clinch it by saying that the RTL dump is not even
complete information about the program. But, did GCC really have to be
written that way?
