 Building it isn't a problem, just editing the 'libstdc++' etc. away from the
'noconfigdirs' for the 'h8300-*' target in the main 'configure.in'.  Then
it will be built for all the multilib-variations.

 The 100+ k executables are too big for H8/300, but the H8/300H and
H8S C++ programs, the almost "Hello World"-level ones I tried with
the simulator in GDB, seemed to work.... Ok, the newlib-routines have
a dummy 'read()' for H8, so no input to the programs worked....

 So my advice is to build the libstdc++.a's and to try them....  BTW, the
official prebuilt Hitachi-distribution, 'gcc-2.96-000821' or something
does include the 'libstdc++.a's, so the people in the GNU-H8 maillist
may have some experience already....

Cheers, Kai
