Version of gcc for LibreOffice

IIUC, the discussion was about compiling LibreOffice master when ...

It happens that as a user of debian-wheezy, which supplies gcc 4.7.2,
I can sadly report that several .cxx files within LibreOffice provoke
the compiler to complain ...

     internal compiler error: Segmentation fault.  Please submit a full
     bug report ...

At least some of the failing source lines had a OUStringLiteral
parameterized by a static const sal_Unicode.

My solution was to build gcc 5.2.0 from source and to this and its
libraries to build LibreOffice.  To run the program in wheezy, I need
to set LD_LIBRARY_PATH to find the 5.2.0 libraries.

Additionally, include/canvas/propertysethelper.hxx:52 provoked
gcc 4.7.2 to say ...

     error: '<::' cannot begin a template-argument list
