Problem solved (more or less). The error messages: fu000001.o(.idata3ドル+0xc): undefined reference to `_libc_iname' fu000002.o(.idata3ドル+0xc): undefined reference to `_libc_iname' etc occur because cc is being called with the -lC switch (ie. linking against C++ libraries!). And this occurs because of an AC_CHECK_LIB macro in configure.in.
