6 dnl AM_PATH_NSPR([MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
7 dnl Test for NSPR, and define NSPR_CFLAGS and NSPR_LIBS
8 dnl
9 dnl If the nspr-config script is available, use it to find the
10 dnl appropriate CFLAGS and LIBS, and to check for the required
11 dnl version, and run ACTION-IF-FOUND.
12 dnl
13 dnl Otherwise, if NO_NSPR_CONFIG_SYSTEM_VERSION is set, we use it,
14 dnl NO_NSPR_CONFIG_SYSTEM_CFLAGS, and NO_NSPR_CONFIG_SYSTEM_LIBS to
15 dnl provide default values, and run ACTION-IF-FOUND.  (Some systems
16 dnl ship NSPR without nspr-config, but can glean the appropriate flags
17 dnl and version.)
18 dnl
19 dnl Otherwise, run ACTION-IF-NOT-FOUND.
