I don’t think there’s any way to change that without touching the source.

Probably, but you probably also want to type “3.14p0” and be read it in 
correctly. That’s more work.

Maxima already as a compiler builtin, so put your changes in a file and 
do something like:

|(%i1) :lisp (load "/path/new-code.lisp") |

Or

|(%i1) :lisp (load (compile-file "/path/new-code.lisp")) |
