1 | dnl @synopsis AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) | ||
2 | dnl | ||
3 | dnl This macro _AC_DEFINEs VARNAME to the expansion of the DIR | ||
4 | dnl variable, taking care of fixing up ${prefix} and such. | ||
5 | dnl | ||
6 | dnl VARNAME is offered as both a C preprocessor symbol, and an output | ||
7 | dnl variable. | ||
8 | dnl | ||
9 | dnl Note that the 3 argument form is only supported with autoconf 2.13 | ||
10 | dnl and later (i.e. only where _AC_DEFINE supports 3 arguments). | ||
11 | dnl | ||
12 | dnl Examples: | ||
