You're right!
In addition to setting GCC_DEFAULT_VERSION to 4.7, one also needs
to adjust the following in Mk/bsd.gcc.mk:
. if ${_USE_GCC} == ${GCC_DEFAULT_VERSION}
_GCC_PORT:= gcc
. else
_GCC_PORT:= gcc${V}
. endif
The most correct way of doing this would be replacing the first line by
. if ${_USE_GCC} == 4.6
That should then do the right thing; or you could just remove everything
except for
_GCC_PORT:= gcc${V}
Either should work.
(I'd love to update GCC_DEFAULT_VERSION to 4.7 one of these days; is
the cluster sufficiently recovered for a test run?)

Hi Gerald
I've now run ia64 with the above change for over 2 weeks,
mostly rebuilding ports, etc.
I didn't see any issues with gcc47.
So, from my very limited testing,
gcc47 can be made default.
Also, I saw that gcc48 is released.
Do you have any plans to make gcc49 port?
Anton
