--- Comment #7 from Jan Dubiec <jdx at o2 dot pl> ---
OK, I have applied the patch manually to my 12.2.0 tree and libstdc++ has been
partially build. "Partially" because everything seems to be fine for H8/300H,
H8S and H8SX in "advanced mode" (let's call it "32-bit mode") but compilation
fails (in the same file!) in "normal mode" ("16-bit mode"). Note the -mn
option:

BTW. I can see -mn option above but AFAIK it has to be used with -mh or -ms or
-msx. So how the build system passes one of these options to the cross
compiler?
