I'm sure a modern compiler would have no problem with it, but in 1980 optimizer technology wasn't there yet. Modern compilers use more memory that engineers would dare dream of in 1980.
By having no problem I mean we know enough about writing an optimizer to write such a thing. I don't think any compiler does, just that they could.
