Fixes <https://bugs.gnu.org/28956>. Reported by Leo Famulari <leo@famulari.name>. * build-aux/build-self.scm (build): Add (guix build compile) to #:modules. * guix/build/pull.scm (build-guix): Wrap 'compile-files' call in 'with-directory-excursion'. Strip "./" from FILES when passing it to 'compile-files'.

;;; builds it.

|
||
;;; This file uses modules provided by the already-installed Guix. Those
|
||
;;; modules may be arbitrarily old compared to the version we want to
|
||
;;; build. Because of that, it must rely on the smallest set of features
|
||
;;; that are likely to be provided by the (guix) and (gnu) modules, and by
|

;;; Guile itself, forever and ever.
