🚀 go-pugleaf

The configuration is: sun4-os4, set up by first make maketest; 
config.g++ sun4-os4; make; it missed to link fold-const.c to g++ 
directory, other than that it worked to produce g++, I then installed g++.
compile libg++, the g++-1.35- failed at the first function (builtin.cc) and 
report  get fatal signal 6.
The g++-1.35- is compiled by gcc-1.34.91, gcc passed stage2 check without any
problem. (One problem in install gcc is I need a link of tm.h to config 
directory, also the copy I got seems have a few EOF in the middle of 
fixincludes). Do I need change any thing in compile of g++? Any one has 
installed g++-1.35-?i]
Also where can I get a copy of matrix class? I would like to try it out.
