Hi Guix, I snarfed these from my cc-for-target branch. Examples of generated commit messages, without any massaging: gnu: ufoai-data: Use 'cc-for-target' and friends. * gnu/packages/games.scm (ufoai-data) [arguments]<#:configure-flags>: Use the C cross-compiler, instead of hardcoding "gcc". Use the C++ cross-compiler, instead of hardcoding "g++". gnu: mlt: Use 'cc-for-target' and friends. * gnu/packages/video.scm (mlt) [arguments]<#:make-flags>: Use the C cross-compiler, instead of hardcoding "gcc". Use the C++ cross-compiler, instead of hardcoding "g++". gnu: theorafile: Use the C cross-compiler. * gnu/packages/video.scm (theorafile) [arguments]<#:make-flags>: Use the C cross-compiler, instead of hardcoding "gcc". [arguments]<#:phases>{check}: Only run tests when not requested. etc/comitter.scm.in should probably do some line wrapping as well. WDYT? Greetings, Maxime.
