[bug#30411] [PATCH] gnu: ldc: Update to 1.7.0.

[Pjotr Prins <pjotr.public12@thebird.nl>]

[-- Attachment #1: Type: text/plain, Size: 229 bytes --]

Thanks Danny. Attached a patch that works for me for a latest checkout
of master. I used invoke, added some comments, ran lint and fixed the
datetime issue. Strangely it bails outside the phobos testing. 

Hope that helps.

Pj.

-This patch deactivates some tests that fail when ldc is built with the command:
-
-./pre-inst-env guix environment guix --pure -- ./pre-inst-env guix build ldc@1.1.0-beta6
-
-When the --keep-failed flag is added to the build command above, and the tests
-run in the resulting /tmp/guix-build-ldc-1.1.0-beta6.drv-* directory, the tests
-pass.
