SGI IRIX gcc 4.7

[Carlo Pisani]

hi
I am trying to build gcc v4.7 on a remote IRIX machine (not my
property, thus I can't access it 24h/7) with these (1) gnu-files,
patch, and scrips (you can see how things are configured for
compilation)

I am stopped at the ppl v0.11 stage with the following error that I am
not able to understand neither to solve

any hint?

thanks
