Peter,

I would not recommend your method.  But to each his own.

gcc5 is available on SBo, as well as avr-gcc.  They integrate into the system much nicer than your method.

Another option is to do the old "./configure; make; make install" but target /opt/gcc<ver> as the DESTDIR.  I did this on Slackware 14.2 with newer versions of GCC for use with MATLAB.
