+	  option to turn off the welcome banner.
+
+Thu Mar 23 03:12:11 1995  Phil Nelson  <phil@cs.wwu.edu>
+
+	* util.c: Corrected a comment.
+
+Tue Mar 21 13:36:24 1995  Phil Nelson  <phil@cs.wwu.edu>

+	  in non-POSIX mode.
+
+Tue Mar 21 09:38:28 1995  Phil Nelson  <phil@cs.wwu.edu>
+
+	* execute.c, main.c, util.c: Add support for user

+
+Mon Mar 20 23:23:34 1995  Phil Nelson  <phil@cs.wwu.edu>
+
+	* number.c, proto.h, execute.c, storage.c, dc-number.c:
+	  Changes to bc_add and bc_sub parameters to allow for
+	  different scale results than were possible.  This is
+	  for correct implementation of modulo.  All calls were
+	  updated.
+
+Mon Mar 20 19:26:06 1995  Phil Nelson  <phil@cs.wwu.edu>
+
+	* sbc.y: Removed second parameter on calls to arg_str to match

+
+Tue Feb 28 14:30:18 1995  Phil Nelson  <phil@cs.wwu.edu>

+	  only when the -s flag is given.  Otherwise it does the tradational
+	  thing.
+
+	* dc-misc.c: Add the "std_only" flag, always set to zero.  This is
+	  needed due to the above change.

+	  work.
+
+	* configure.in: added shell commands to get configure to work
+	  correctly in directories other than srcdir.
+
+Wed Nov  2 10:18:19 1994  Phil Nelson  (phil@cs.wwu.edu)
+
+	* bc.1 bc.y bcdefs.h const.h execute.c global.c global.h load.c

+
+	* configure.in, Makefile.in, acconfig.h: Add support for autoconf.
+	  Removed old Makefile.
+
+Wed Jul 20 22:46:32 1994  Phil Nelson  (phil@cs.wwu.edu)
+
+	* bc.y: change definition of next_label in function definition.

+
+Fri Apr  8 14:16:37 1994  Phil Nelson  (phil@cs.wwu.edu)
+
+	* Makefile: Change the distribution to include libmath.h.dist

+Sun Feb 13 01:08:14 1994  Phil Nelson  (phil@cs.wwu.edu)

+
+Wed May 19 15:15:12 1993  Phil Nelson  (phil at cs.wwu.edu)
+
+	* number.c: Fixed output of negative numbers in bases other than
+	  base 10.
+
+Wed Apr 21 11:56:31 1993  Phil Nelson  (phil at cs.wwu.edu)
+
+	* bc.1: Changed Steve Sommars e-mail address.
+
+Wed Apr 14 12:13:39 1993  Phil Nelson  (phil at cs.wwu.edu)

+
+Thu Mar 11 15:34:34 1993  Phil Nelson  (phil at cs.wwu.edu)

+
+Mon Mar  1 14:00:46 1993  Phil Nelson  (phil at cs.wwu.edu)
+
+	* util.c: (nextarg) changed parameter "val" to be an int.
+
+Tue Feb 16 10:06:45 1993  Phil Nelson  (phil at cs.wwu.edu)
+
+	* util.c: (call_str, arg_str) added a function call_str that
+	  correctly produces the string of argmuent types for a function
+	  call.  arg_str produced them in the reverse order.  This
+	  eliminated the need for the "comma" argument to arg_str, which
+	  was removed.
+
+	* bc.y: changed the calls to arg_str to have only one parameter
+	  in the function definition rule and replaced the call to arg_str
+	  with call_str in the function call rule.
+
+Tue Nov 24 17:38:40 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* Makefile: Added LEXLIB definitions for use with lex.
+
+Thu Oct 22 13:43:16 1992  Phil Nelson  (phil at cs.wwu.edu)

+	  the computation by not doing unneeded multiplications.
+
+Wed Sep 30 10:43:52 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* global.h: Fixed documentation.
+
+Tue Sep 29 15:27:50 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* storage.c (process_params): Changed processing of more arguments
+	  than in a function definition to just a return.  
+
+	* Makefile: Made changes to make it more in conformance with the
+	  GNU coding standards.
+
+Tue Jul  7 21:09:07 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* (const.h, bc.y, util.c) Added code so that when the math
+	  library is loaded, redefinition of any math library function
+	  will not cause the other functions to quit working correctly.
+	  Before this change, redefining a(x) would cause s(x) and c(x)
+	  to quit working and redefining s(x) would cause c(x) to quit
+	  working.
+
+Wed Jul  1 14:35:29 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* (libmath.b) Changed the calculation of scale for computing
+	  e(x) and l(x).  This provides a little more accuracy in the
+	  last digit at the expense of a little speed.
+
+	* (Test/checklib.b) Changed tests to be parameterized and test
+	  more values.
+

+
+	* (configure) changed the script from looking in the
+	  include directory for a .h file to asking cc (gcc) to
+	  find the .h file.  This will allow better detection
+	  of include files available to the C compiler.
+
+Wed Jun 24 22:11:37 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* (bc.y) Added a warning for the "last" variable.
+
+	* (scan.l) Added code to allow for a single dot (.) to be the
+	  same as the variable "last".  This is not a "standard" feature,
+	  but is provided for those who want it.
+
+	* (Install) Documented the new define for dot (.).
+
+	* (bc.1) Documented the use of dot (.) for "last".
+
+	* (Makefile) Added an easy method for adding extra defines for
+	  use during the compile.  Set DOT_IS_LAST as a standard
+	  extra define.
+
+	* (number.c) Changed the code for sqrt for better speed.
+
+Mon Jun 22 21:47:05 1992  Phil Nelson  (phil at cs.wwu.edu)
+
+	* Changed the name of math.h to libmath.h to avoid conflict
+	  with /usr/include/math.h.  Changed all references to math.h
+	  to libmath.h in all files.
+
+	* (configure) Changed the test for long strings accepted by
+	  cc to not include libmath.h and thus not need to distribute
+	  a file that is generated by the system.
+
+	* (Makefile) Changed PREFIX, BINDIR, LIBDIR, and MANDIR to
+	  lower case.

+	  after an error has been found.

+	  (before the close quote) to work correctly.  Also added code to
+	  report illegal characters in a more readable output format.

+	* (bc.1) Added the exclusion of NUL characters from strings in
+	  the "differences" section and updated date of last change.
+
+	* (const.h) Changed BC_MAX_SEGS to 16.

+	  size for bases greater than 16.  e.g.  For base 1000, each
+	  "digit" is a three digit number.
+
+	* (Makefile) Added the "8" flag to get an 8 bit scanner.
+
+	* (scan.l) Changed "char *" to "unsigned char *" to match the

+	  math.h in the distribution for use by configure.  Included
+	  ChangeLog in the distribution.
