Hi,
I've tried to build 12-stable r358547 for MIPS using mips-gcc9-9.2.0
(gcc 6.5.0 is available but out of date and probably will be removed
from ports tree in some future).
12-stable can't be compiled with such gcc version right now, so here
is a list of errors and patches taken from HEAD that helped me to do
build it.
This is in case someone wants to do the same at least:
- The first build error was:

I do not know the policy about GCC architectures, but it would be
great to make them buildable with GCC version up to date.
