GCC Version Questions

[Sebastian Huber]

I would rather use GCC 4.6.X for the RTEMS 4.11 release on ARM since I had a 
lot of trouble with earlier version of GCC 4.6.  I worked with GCC 4.6 during 
the whole 4.11 development cycle and I am really at unease to use an untested 
GCC 4.7 for this release.

Most ARM BSPs use ARMv4T and ARMv5T.  The focus at GCC is currently at more 
recent architecture versions like ARMv7.  My impression is that the older 
versions receive little testing and attention by the GCC developers.  So 
progress breaks older versions sometimes.

In general we should consider to select a certain GCC version for an upcoming 
RTEMS release and stick with this GCC version for this RTEMS release.  Thus we 
continuously work with a particular GCC release during development and can 
address all compiler issues in this phase.
