(Full diff reproduced at the end of this message.)
I can report these results after running a test build on amd64:
* I don't know if this is expected, but something still pulls in
gcc/4.9.
* lang/gprolog hung.
gplc -c --fast-math fd2c.pl
KILLED: build stuck at 47% frozen for 60mn
* Some ports depending on devel/riscv-elf/gcc can't be built because
it conflicts with gcc/6,-libs:
/usr/local/lib/libcc1.la (gcc-libs-6.4.0p2 and riscv-elf-gcc-8.1.0p0)
/usr/local/lib/libcc1.so.0.0 (gcc-libs-6.4.0p2 and riscv-elf-gcc-8.1.0p0
* Some ports depending on devel/avr/gcc can't be built because it
conflicts with gcc/6,-libs:
/usr/local/lib/libcc1.la (gcc-libs-6.4.0p2 and avr-gcc-5.4.0p1)
/usr/local/lib/libcc1.so.0.0 (gcc-libs-6.4.0p2 and avr-gcc-5.4.0p1)
(Obviously this implies that riscv-elf/gcc and avr/gcc already
conflict with each other. A known problem.)
That's it on amd64.
The much bigger question is how gcc6 will fare on the non-clang
archs that would use if for all C++ ports. In principle I agree
that gcc4.9 is too old and a new compiler will be required for newer
C++ code. In practice, I don't know who can take charge of this
change.
Here's the diff I tested:
