+  formatdata.c: if possible, and assuming doubles must be aligned on
+double boundaries, use existing holes in DATA for common blocks to
+force alignment of the block.  For example,
+	block data
+	common /abc/ a, b
+	double precision a
+	integer b(2)
+	data b(2)/1/
+	end
+used to generate
+	struct {
+	    integer fill_1[3];
+	    integer e_2;
+	    doublereal e_3;
+	    } abc_ = { {0}, 1, 0. };
+and now generates

+	    doublereal fill_1[1];
+	    integer fill_2[1];
+	    integer e_3;
+	    } abc_ = { {0}, {0}, 1 };
+In the old generated C, e_3 was added to force alignment; in the new C,
+fill_1 does this job.

+  libi77: move e_wdfe from sfe.c to dfe.c, where it was originally.
+Why did it ever move to sfe.c?

+  Treat dreal as a synonym for dble unless -cd is specified on the
+command line.
+
+Sun Sep 13 22:23:41 EDT 1998
+  format.c: fix bug in writing prototypes under f2c -A ... *.P:
+under some circumstances involving external functions with no known
+type, a null pointer was passed to printf.
+
+Tue Oct 20 23:25:54 EDT 1998
+  Comments added to libf2c/README and libF77/README, pointing out
+the need to modify signal1.h on some systems.
+
+Thu Nov 12 15:34:09 EST 1998
+  libf77, libf2c.zip: minor tweaks to [de]time_.c and the makefiles,
+so makefile.sy, makefile.vc, and makefile.wat deal with [de]time_.c.
+
+Wed Feb 10 22:59:52 EST 1999
+  defs.h lex.c: permit long names (up to at least roughly
+MAX_SHARPLINE_LEN = 1000 characters long) in #line lines (which only
+matters under -g).
+  fc: add -U option; recognize .so files.
+
+Sat Feb 13 10:18:27 EST 1999
+  libf2c: endfile.c, lread.c, signal1.h0: minor tweaks to make some
+(C++) compilers happier; f77_aloc.c: make exit_() visible to C++
+compilers.  Version strings not changed.
+
+Thu Mar 11 23:14:02 EST 1999
+  Modify f2c (exec.c, expr.c) to diagnose incorrect mixing of types
+when (f2c extended) intrinsic functions are involved, as in
+(not(17) .and. 4).  Catching this in the first executable statement
+is a bit tricky, as some checking must be postponed until all statement
+function declarations have been parsed.  Thus there is a chance of
+today's changes introducing bugs under (let us hope) unusual conditions.
+
+Sun Mar 28 13:17:44 EST 1999
+  lex.c: tweak to get the file name right in error messages caused
+by statements just after a # nnn "filename" line emitted by the C
+preprocessor.  (The trouble is that the line following the # nnn line
+must be read to see if it is a continuation of the stuff that preceded
+the # nnn line.)  When # nnn "filename" lines appear among the lines
+for a Fortran statement, the filename reported in an error message for
+the statement should now be the file that was current when the first
+line of the statement was read.
+
+Sun May  2 22:38:25 EDT 1999
+  libf77, libi77, libf2c.zip: make getenv_() more portable (call
+getenv() rather than knowing about char **environ); adjust some
+complex intrinsics to work with overlapping arguments (caused by
+inappropriate use of equivalence); open.c: get "external" versus
+"internal" right in the error message if a file cannot be opened;
+err.c: cast a pointer difference to (int) for %d; rdfmt.c: omit
+fixed-length buffer that could be overwritten by formats Inn or Lnn
+with nn > 83.
+
+Mon May  3 13:14:07 EDT 1999
+  "Invisible" changes to omit a few compiler warnings in f2c and
+libf2c; two new casts in libf2c/open.c that matter with 64-bit longs,
+and one more tweak (libf2c/c_log.c) for pathological equivalences.
+  Minor update to "fc" script: new -L flag and comment correction.
+
+Tue May  4 10:06:26 EDT 1999
+   libf77, libf2c.zip: forgot to copy yesterday's latest updates to
+netlib.

 Current timestamps of files in "all from f2c/src", sorted by time,
 appear below (mm/dd/year hh:mm:ss).  To bring your source up to date,
 obtain source files with a timestamp later than the time shown in your
 version.c.  Note that the time shown in the current version.c is the
 timestamp of the source module that immediately follows version.c below:
