# AX_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) |

# DESCRIPTION |
| 10 |
# |
| 11 |
# This macro sets VARNAME to the expansion of the DIR variable, taking |
| 12 |
# care of fixing up ${prefix} and such. |
| 13 |
# |
| 14 |
# VARNAME is then offered as both an output variable and a C preprocessor |
| 15 |
# symbol. |
| 16 |
# |
| 17 |
# Example: |
| 18 |
# |
| 19 |
# AX_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.]) |

dnl In Autoconf 2.60, ${datadir} refers to ${datarootdir}, which in turn |
| 42 |
dnl refers to ${prefix}. Thus we have to use `eval' twice. |
