| Then octave-2.1.7 compiles OK with egcs-1.1b.

I know there was a problem with egcs 1.1 such that it failed to
compile some stuff in sys/wait.h, but this patch can't be the right
way to fix the problem.  I've been told the problem will be fixed in
egcs 1.1.1.

| I made also a binary-dist. The binary-dist has problems:
| 
| 1) Error message when trying to plot:
| error: plot: unable to open pipe to `gnuplot'
| 
| 2) 'ls' gives
| error: couldn't start process for ls!
|  
| Both 1) and 2) were at first also present in the directly installed 
| version, but went away after a re-compilation. I don't understand why.

I don't have a clue.

| 3) 'max(1,2)' gives
| error: `max' undefined near line 1 column 1
| error: evaluating index expression near line 1, column 1

Was this still a problem after the install-octave script was fixed and
the .oct files were installed in the right directories?

| 4) In order to install the binary distribution, I had to patch the
| install-octave script: There is a spurious 'cd src' that keeps the *.oct
| files
| from being copied:

|      for f in $oct_files

This is fixed in 2.1.8.

OK, I'll have a look at fixing this.  I think the quick solution is to
make some symbolic links.

Thanks,
