RE: Gcc3.2 build error on Solaris 10

["Bill McEnaney" <bill at rkirkpat dot net>]

Hey, Folks,

I think my Sunblade 100, which runs Solaris 8, has built Gcc3.2.  So if
anybody wants me to try to build it, I'll be happy to do that.  Sadly,
the poor ol' guy is a slow poke, who probably thinks aslmost as slowly
as my spastic fingers type.  :)  Since Tamino, the workstation, has
tured six this month, he;s a senior citizen.  ;)
