civodul pushed a commit to branch core-updates
in repository guix.
commit 9bf3ced06c42700d6c83ce3a0eda244798104618
Author: Ludovic Courtès <address@hidden>

packages: 'package-transitive-supported-systems' accounts for implicit
inputs.
Reported by Federico Beffa.
* guix/packages.scm (package-transitive-supported-systems): Use
bag-direct-inputs + package->bag rather than package-direct-inputs.
* tests/packages.scm ("package-transitive-supported-systems"): Add
explicit 'build-system' field to each 'dummy-package' form.
("package-transitive-supported-systems, implicit inputs"): New test.
