[Gm2] Status of builds on x86 and ARM using gcc-4.7.3+gm2-cvs-latest.tar.gz (27-Sep-2013)

[JD]

1. Building
 I've built native compilers on x86 with Ubuntu 13.04 and on ARM (i.e. 
Raspberry Pi) with Raspbian from gcc-4.7.3+gm2-cvs-latest (27-Sep-2013).
By 'built' I mean I've run configure, make and make-install and this 
created a new binary file gm2 in $HOME/opt/bin.  The Ubuntu make ended 
with just "leaving directory" output but the Raspbian make ended with 
Errors 1 & 2.

2.  Testing
I've found the reason for the cc1plus error (thanks for the strong hint, 
Gaius!).  I hadn't set GM2_ROOT to ~/opt (or to anything in fact).

a) Ubuntu
'hello world' compiles and executes.  However, a similar simple module 
does not compile.  It should display the lengths of all the multi-sized 
types, e.g. INTEGER64.  It appears that the built file 
~/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/gm2/iso/SYSTEM.def does not 
contain the full list of types, e.g. INTEGER64, whereas the file that 
comes when you install the gm2 package, 
/opt/gm2/lib/gcc/i486-linux-gnu/4.1.2/gm2/iso/SYSTEM.def, does have 
these multi-sized types defined.

b) Raspbian on Pi
'hello world' does not compile.  It failed to find SYSTEM.def even after:
      export GM2_ROOT=~/opt

The immediate problem is that the library is incomplete.  For example, 
there is NOT a gm2 directory in 
~/opt/lib/gcc/armv6l-unknown-linux-gnueabihf/4.7.3/
I can see that gcc-4.7.3+gm2-cvs-latest/gcc/gm2/gm2-libs-iso contains 
SYSTEM.def but it doesn't have StrIO.def, so I'll not try this route 
anymore.
