;;;; Note that the recommended way to customize the features of a
;;;; local build of SBCL is not to edit this file, but instead to
-;;;; tweak customize-target-features.lisp. If you define a function
-;;;; in customize-target-features.lisp, it will be used to transform
-;;;; the target features list after it's read and before it's used.
-;;;; E.g. you can use code like this:
+;;;; tweak customize-target-features.lisp. (You must create this file
+;;;; first; it is not in the SBCL distribution, and is in fact
+;;;; explicitly excluded from the distribution in places like
+;;;; .cvsignore.) If you define a function in
+;;;; customize-target-features.lisp, it will be used to transform the
+;;;; target features list after it's read and before it's used. E.g.,
+;;;; you can use code like this:
;;;; (lambda (list)
;;;; (flet ((enable (x) (pushnew x list))
;;;; (disable (x) (setf list (remove x list))))
;; character set.
:sb-unicode
+ ;; Support for a full evaluator that can execute all the CL special
+ ;; forms, as opposed to the traditional SBCL evaluator which called
+ ;; COMPILE for everything complicated.
+ :sb-eval
+
;; Record source location information for variables, classes, conditions,
;; packages, etc. Gives much better information on M-. in Slime, but
;; increases core size by about 100kB.
;; again, if anyone's sufficiently motivated.
; :long-float
+ ;; Some platforms don't use a 32-bit off_t by default, and thus can't
+ ;; handle files larger than 2GB. This feature will control whether
+ ;; we'll try to use platform-specific compilation options to enable a
+ ;; 64-bit off_t. The intent is for this feature to be automatically
+ ;; enabled by make-config.sh on platforms where it's needed and known
+ ;; to work, you shouldn't be enabling it manually. You might however
+ ;; want to disable it, if you need to pass file descriptors to
+ ;; foreign code that uses a 32-bit off_t.
