Please review optional GCC-4.7.1 spkg (#13150)

[Jeroen Demeyer]

For testing purposes, or just to have the latest GCC, some people might
prefer GCC-4.7.1 over the Sage-shipped GCC-4.6.3. That's why I created
an optional GCC-4.7.1 spkg.

The spkg is exactly the same as the GCC-4.6.3 spkg currently in Sage,
except for the src/ directory. Just for fun, I tested it on Solaris and
it works.

This is now updated to GCC-4.7.2 and needs review as *optional* package:

This is now updated to GCC-4.7.2 and needs review as *optional* package:

I wanted to try this on a Sage 5.4 beta 1 (upgraded from Sage 5.3 binary) on Ubuntu 12.04 64 bit, and here's what I get:

Error installing package gcc-4.7.2

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the relevant part of the log file
  /home/andrea/Scrivania/Torrent/sage/spkg/logs/gcc-4.7.2.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/home/andrea/Scrivania/Torrent/sage/spkg/build/gcc-4.7.2 and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd '/home/andrea/Scrivania/Torrent/sage/spkg/build/gcc-4.7.2' && '/home/andrea/Scrivania/Torrent/sage/sage' -sh)
When you are done debugging, you can type "exit" to leave the subshell.

Am I missing something? I tried to search online but the only suggestion I got is to install gcc, gfortran or g++ all of which I already have.

Thank you,
