The recent fix for ITS # 5888 unmasked this presumably long-standing issue.
uuid_create and uuid_unparse_lower are used without autoconf verifying them
first. An up-to-pat
ch Solaris 9, in particular, is an example of a platform where uuid_generate
exists without uuid_unparse_lower. Google seems to show that older Linux ~2006
has a similar situation.
