Jim Warner 5e46a145ba library: ensure any 'flags' is consistently 'unsigned'
This commit is an outgrowth of the research into a bug
that recently surfaced with the 'w' program. And while
that program was just a victim several inconsistencies
were found in the handling of library flags during the
research. This patch just address such irregularities.
