building 2.0.1 sunOS4.1.3

[Djossou Coco 0251858170]

Hello,
Building octave-2.0.1 on SPARCstation-10 sunOS4.1.4 stops on the file
sighandlers.cc in src directory.
./configure --prefix=/usr/local/gnu > & ../configure.log
make CFLAGS=-O CXXFLAGS=-O LDFLAGS= > & ../all.log

-rw-r--r--   1 djossou  staff       20116 Jan 21 12:23 configure.log
The output of ./configure and make are available
I can grep information in them if it could help.
Any idea will be welcome,
Thanks in advance,
Coco D.
