The code was added into the Cygnus repository on 6-Jan-99 so I'll hazard
a guess it was for versions of gcc available at that time. If/when the
behavior has stopped I don't know. I think there's a testcase, but
unfortunately I've lost track of the old Cygnus PRMS database. I'll take
a look and see if I can find it. It'd still take some archiving to find
out when/if we stopped doing this :)
