Hi, 
    I just installed gcc 2.7.2 under my home directory, because my
sysadmin is not very responsive.  I try to compile octave 2.0 under
Alpha, but after the compilation goes on flawlessly for a while, I get
file not found errors.  Indeed, g++ does not look in the include dirs
it has set up under my home directory.  That's why I have added this
to the gcc specs file:

 -isystem /usr/users/pot/lib/gcc-lib/alpha-dec-osf3.0/2.7.2/include
 -isystem /usr/users/pot/alpha-dec-osf3.0/include
 -isystem /usr/users/pot/lib/gcc-lib/alpha-dec-osf3.0/2.7.2/include/g++
 -isystem /usr/users/pot/lib/gcc-lib/alpha-dec-osf3.0/2.7.2/include/g++/std
 -isystem /usr/include/g++ -isystem /usr/include/g++/std

This makes the compilation proceed futher, but then it stops with an
error which I don't know how to handle.  I am stuck, because I suspect
a gcc installation problem.  Can you confirm this?  Here is the error,
obtained with a make all in liboctave:

sable$ make all

The strange thing is that there is no `::' in stddef.h.  Here is the
file:
