Hi!
C++20, in particular https://wg21.link/P1120R0 paper voted into it,
deprecates various operations between enumerators from different enumeration
types etc., and as we've switched to -std=gnu++20 by default, this now
results in warnings or errors during stage2 and onwards.
The following patch should fix mips build.
Tested on x86_64 with a cross to mips, by doing
make clean; make -j32 CXXFLAGS='-g -std=gnu++20' in the gcc/ directory.
Ok for trunk?

OK. Similarly for any others you encounter. I know RISC-V has the same
issue and I'd planned to take care of it over the coming days. I
suspect there are others.
