Hi,

I am trying to compile octave-0.70 on a Sun SPARC 2 running SunOs 4.1.1
and gcc/g++ 2.3.3. I am kind of new to unix/gnu, and I am pretty sure  It
must be something totally boneheaded that I am doing. Would really
appreciate any help I can get. 


1) At the beginning, gcc complained about being unable to find various 
   include files. I poked around the system, and gave the following 
   paths (in the given order) :-

   */lib/gcc-lib/sparc/2.3.3
   */lib/g++-include 

   Is this the correct thing to do ?  

2) So it starts compiling, and after some time says :-

   tree.cc: In method `class tree_constant tree_matrix::eval (int)':
   tree.cc:284: parse error before `else'

   The offending piece of code seems to be :-

   281:      direct = list->dir;
   282:      if (list == this)
   283:	assert (direct == tree::md_none);
   284:      else if (first)
   285:	direct = md_none;

   What might I be doing wrong ?
 
   Actually, if I comment out the assert() the compile goes through that
   point. But the documentation that comes with the distribution from 
   ftp.che.utexas.edu says the program should compile fine with gcc 2.3.3
   as it is. (Although they say SunOs 4.1.2, whereas I am using 4.1.1. could
   this make a difference ?)

3) Now if I comment out the assertion, and let it continue, I get a number of
   errors. A couple of samples follow :-

   sample 1
   --------

   In file included from ../bsd-math/log1p.c:97:
   /afs/ir/systems/sun4c_411/newsw/lib/g++-include/errno.h:3: 
      parse error before string constant
   In file included from ../bsd-math/log1p.c:97:
   /afs/ir/systems/sun4c_411/newsw/lib/g++-include/errno.h:22: 
      parse error before `}'


    Here is part of the file <errno.h>  :-

    1:  #ifndef errno_h
    2:
    3:  extern "C" {

    sample 2
    -------- 

   ../bsd-math/log1p.c:114: conflicting types for `finite'
   /afs/ir/systems/sun4c_411/newsw/lib/gcc-lib/sparc/2.3.3/include/math.h:56: 
      previous declaration of `finite'
   ../bsd-math/log1p.c:35: warning: `sccsid' defined but not used
   gmake[1]: *** Error 1

    Here is part of the file "log1p.h" :-

    114: extern double scalb(), copysign(), logb(), finite(), log__L();
