dnl This macro sets VARNAME to the expansion of the DIR variable, |
| 4 |
dnl taking care of fixing up ${prefix} and such. |

dnl |
| 6 |
dnl VARNAME is then offered as both an output variable and a C |

dnl In Autoconf 2.60, ${datadir} refers to ${datarootdir}, which in turn |
| 27 |
dnl refers to ${prefix}. Thus we have to use `eval' twice. |
