            Bug ID: 107883
           Summary: c++17/memory_resource.cc build error for H8/300 target
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org

error log of memory_resource.cc

On building gcc-12.2.0 with newlib-4.1.0 (newlib and libgloss) and
binutils-2.36.1 on Debian-11.5/amd64.

gcc/config/h8300/t-h8300 is modified with:

    MULTILIB_OPTIONS = ms/msx mint32
    MULTILIB_DIRNAMES = h8300s h8sx int32

to disable building H8 normal mode library.

gcc configuration is:

    ../configure --target=h8300-unknown-elf --enable-languages=c,c++ \
    --prefix=/home/uaa/h8300 --with-newlib --disable-nls --disable-libssp \
    --disable-libgomp --disable-libstdcxx-pch \
    --disable-libstdcxx-filesystem-ts --with-newlib --disable-wchar_t

error occurs at libstdc++-v3/src/c++17/memory_resource.cc, due to the
size of int is 16bit (H8/300 default). log is at attachment.

Here is the remedy:
