2023-07-13gnu: netdde: Resurrect and update to 2.6.32.65-2-e67c284ac1....* gnu/packages/patches/netdde-build-fix.patch: New file. * gnu/local.mk (dist_patch_DATA): Add it. * gnu/packages/hurd.scm (netdde)[source]: Update to e67c284ac113d939b10b4578334f27dab29d5b08 and use it. [inputs]: Add zlib:static. [arguments]: Remove #true from build phases. In 'build' phase, remove obsolete CFLAGS, and also build static version. In 'install' phase, install them in <out>/hurd. There is no check target, so set #:tests? to #false. Signed-off-by: Josselin Poiret <dev@jpoiret.xyz> Janneke Nieuwenhuizen
