--- Comment #2 from Matthew Woehlke <mw_triad at users dot sourceforge.net> --- To be clear, you are arguing that distributions of the software can entirely omit the notice because the source code is not distributed? Has that been tested in court, or has Sun Microsystems affirmed this interpretation? Because that is NOT the usual understanding of what is meant by 'preserving this notice'. In fact, if that were the interpretation, the license would be practically irrelevant, which is not likely what Sun intended. Debian, at least, disagrees (see /usr/share/doc/libquadmath0/copyright). Moreover, most corporate lawyers, who typically err on the side of caution, will also disagree. Making it more difficult for users to copy the license notice into their own software which uses libquadmath is actively hostile to those same users (who happen to have said corporate lawyers looking over their shoulders). Please respect the needs of those users.
