| dnl If USE_NLS is yes, it sets BISON_LOCALEDIR to indicate where to find |
| dnl the bison-runtime.mo files and defines YYENABLE_NLS if there are |
| dnl bison-runtime.mo files at all. |
| dnl Also it defines BISON_LOCALEDIR as macro in config.h, that expands to |
| dnl the corresponding C string. |

| dnl Generally, accept an option --with-bison-prefix=PREFIX to indicate where |

| dnl bison in user directories, query the 'bison' program found in $PATH |
| dnl (but not when cross-compiling). |
