dnl Test for NSPR, and define NSPR_CFLAGS and NSPR_LIBS
dnl
dnl If the nspr-config script is available, use it to find the
dnl appropriate CFLAGS and LIBS, and to check for the required
dnl version, and run ACTION-IF-FOUND.
dnl
dnl Otherwise, if NO_NSPR_CONFIG_SYSTEM_VERSION is set, we use it,
dnl NO_NSPR_CONFIG_SYSTEM_CFLAGS, and NO_NSPR_CONFIG_SYSTEM_LIBS to
dnl provide default values, and run ACTION-IF-FOUND. (Some systems
dnl ship NSPR without nspr-config, but can glean the appropriate flags
dnl and version.)
dnl
dnl Otherwise, run ACTION-IF-NOT-FOUND.
