Greetings, it seems that /pkgsrc/lang/gcc3-c++ is broken on Solaris. My 
systems in Ultra10 running Solaris 9, I have successfuly compiled and 
installed /pkgsrc/lang/gcc3-c however when I try to compile a C++ 
compiler, when it comes to building libstdc++-v3 the "configure" script 
seems to enter infinite loop, i.e. it keeps running the same checks over 
  and over again. Below is some of the output, after those line, it 
loops from the start again, and again. Has anyone had similar problems 
before, and how did you fix them??
