[bug#53878] [RFC PATCH 5/9] gnu: Add stex.


From: Philip McGrath
Subject: [bug#53878] [RFC PATCH 5/9] gnu: Add stex.
Date: Tue, 8 Feb 2022 10:18:53 -0500

* gnu/packages/chez-and-racket-bootstrap.scm (stex-bootstrap): New
variable.
(stex): Change from origin to package inheriting from 'stex-bootstrap'.
(chez-scheme)[native-inputs]: Add 'stex-bootstrap'. Remove
labels. Remove dependencies of stex-bootstrap.
[inputs]: Remove labels.
[arguments]: Adapt to use 'stex-bootstrap', 'search-input-file', and
G-expressions.
(nanopass): Make it public as a temporary workaround for Racket.
* gnu/packages/racket.scm
(racket-bootstrap-chez-bootfiles)[native-inputs]: Update accordingly.
