This line in maint.mk: VC-tag = git tag -s -m '$(VERSION)' -u '$(gpg_key_ID)'
does appear to be unused, because its syntax is wrong: there's no message (argument to -m), or equivalently, no tag name is specified. Is something like: VC-tag = git tag -s -m 'Sign version $(VERSION)' '$(VERSION)' -u '$(gpg_key_ID)' intended? -- http://rrt.sc3d.org
