Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
Because textproc/html2text's Makefile does not explicitly set its C++
standard, this leads to several errors:
/usr/local/lib/bison.cc:429:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
register int yystate;
^~~~~~~~~
/usr/local/lib/bison.cc:430:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
register int yyn;
^~~~~~~~~
/usr/local/lib/bison.cc:431:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
register short *yyssp;
^~~~~~~~~
/usr/local/lib/bison.cc:432:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
register YY_HTMLParser_STYPE *yyvsp;
^~~~~~~~~
Add USE_CXXSTD=gnu++98 to avoid these errors.
