Comment(by nbruin):
== Avoiding patching ECL ==
The role of {{{defvar}}} is 2-fold: It declares a variable to have dynamic
scoping rather than lexical scoping and it sets the value ''only'' if the
variable wasn't bound already. So, as long as we execute the two defvar
statements
{{{
(defvar c::*ecl-include-directory* (namestring (make-pathname :directory
(append (butlast (pathname-directory (translate-logical-pathname "SYS:"))
2) '("include")))))
(defvar c::*ecl-library-directory* (namestring (make-pathname :directory
(append (butlast (pathname-directory (translate-logical-pathname "SYS:"))
2) '("lib")))))
}}}
before the compiler package is loaded, our values will persist. So, if one
finds another file of lisp instructions that are guaranteed to be executed
upon ECL startup ({{{~/.eclrc}}} doesn't work because maxima is built by
calling {{{ecl -norc}}}) we're still good. I was not able to find such a
file.
