+ * configure.in: Check for -fexceptions.
+ * config.make.in: Define exceptions, not no-exceptions.
+ * misc/sys/cdefs.h: Define __PMS. When using modern g++ define
+ __P to use throw().
+ * misc/Makefile: Define CFLAGS-tsearch.c and CFLAGS-lsearch.c to
+ $(exceptions).
+ * stdlib/Makefile: Likewise for bsearch.c, msort.c, and qsort.c.
+ * misc/search.h: Use __PMS in tsearch, tfind, tdelete, twalk, tdestroy,
+ lfind, and lsearch prototpypes.
+ * stdlib/stdlib.h: Likewise for bsearch and qsort.
