[ECOS] problems compiling host tools

[Aldo Dolfi]

Thanks Jonathan, I indeed had used "make" alone.
Now I tryed to rebuild the tools on another machine (simply copying them 
didn 't work because of different system libraries). Unluckily, I got 
errors similar to the other ones, but this time I followed the 
instruction, I believe. This document
http://sources.redhat.com/ecos/tools/linux-v850-elf.html
says to use a snapshot more recent than 2000-03-20. I thought gcc-2.95.3 
would be fine, as it's newer.

I did

../src/gcc-2.95.3/configure --target=v850-elf --prefix=/ecos/tools 
--exec-prefix=/ecos/tools/H-i686-pc-linux-gnu --with-gnu-as 
--with-gnu-ld --with-gnulib -v | & tee configure.out

make -w all-gcc install-gcc LANGUAGES="c c++" | & tee make.out

I attach the last part of make output

What's weird is that I think these are exactly the same steps I follow 
on the other machine to build the v850 gcc. The other machine is a 
Debian unstable system, whereas the one on which I am trying to work now 
is a RedHat 7.2 (but using gcc-2.95.3 as the native compiler)

Any ideas?
TIA

Aldo
