+ * 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.
+
+1998-06-26 Ulrich Drepper <drepper@cygnus.com>
+
+ * sysdeps/i386/fpu/bits/mathinline.h (__finite): Use C code, not asm.
+
+1998-06-25 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
+
+ * Makefile (remove-old-headers): Make phony.
+
+ * configure.in: Substitute @old_glibc_headers@.
+
+1998-06-26 Ulrich Drepper <drepper@cygnus.com>
+
+ * libc.map: Remove __libc_uid.
+

+
+ * manual/terminal.texi (Allocation, Pseudo-Terminal Pairs): Fix
+ typos.
+
+1998-06-26 Ulrich Drepper <drepper@cygnus.com>
+
+ * libc.map: Add Alpha-specific io function from protected namespace.
