| 173 | dnl THREAD_LIBS_LOCAL --- linker options for use in this source tree |
| 174 | dnl THREAD_LIBS_INSTALLED --- linker options for use after this package |
| 175 | dnl is installed |

| 187 | dnl 2) once the whole package has been installed, users should |

| 191 | dnl to link programs against guile, the GUILE_WITH_THREADS macro |
| 192 | dnl needs to supply the second piece of information as well. |
