+1998-07-29  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c, fnmatch.c: New versions from the GLIBC folks (Ulrich
+	Drepper).  Fixes a bug reported by Eli Zaretski.  Integrates
+	DOS/Windows32 support.
+
+1998-07-27  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>
+
+	* glob.c (glob): Cast away const on assignment of pattern to dirname.
+	Cast the return type of __alloca() for traditional C compilers.
+
+1998-07-23  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c, fnmatch.c: New versions of these files from the GLIBC
+	folks (Ulrich Drepper).  Had to re-integrate some DOS/Windows
+	code.
+
+1998-07-10  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c (glob_in_dir): If no meta chars exist in PATTERN and
+	GLOB_NOCHECK is present, don't look for the file--whether it's
+	found or not, we'll always return it, so why bother searching?
+
+	Also, if we are searching and there are no meta chars, don't
+	bother trying fnmatch() if the strcmp() fails.
+
+1998-05-30  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* glob.c (glob) [__MSDOS__, WINDOWS32]: Compute the directory and
+	filename parts of the pattern correctly when it includes a drive
+	spec.  Disallow wildcards in the drive spec.  Prevent recursion
+	when dirname is of the form "d:/" or "d:".
+	(prefix_array) [__MSDOS__, WINDOWS32]: Don't append a slash to
+	"d:/" and "d:".
+
+1998-05-13  Paul D. Smith  <psmith@gnu.org>
+
+	* SMakefile, Makefile.ami, glob.c, glob.h, fnmatch.c: Updated from
+	the latest glibc version.
+
+1998-04-17  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Create a config.h file instead of setting things
+	on the compile line.  This is because when build.sh runs it merely
+	passes -DHAVE_CONFIG_H to the glob files, just as it does to the
+	make files.
+	* config.h.in: Created by autoheader.
+
 Tue Aug 12 10:52:34 1997  Paul D. Smith  <psmith@baynetworks.com>
 
 	* configure.in: Require autoconf 2.12.
