Thu Jul 14 17:55:46 EDT 1994
  Fix glitch in changes of 6 July 1994 that could cause erroneous
"division by zero" warnings (or worse).  Example:
	subroutine foo(a,b)
	y = b
	a = a / y	! erroneous warning of division by zero
	end

Mon Aug  1 16:45:17 EDT 1994
  libi77: lread.c rsne.c: for benefit of systems with a buggy stdio.h,
declare ungetc when neither KR_headers nor ungetc is #defined.

Wed Aug  3 01:53:00 EDT 1994
  libi77: lwrite.c (list output): do not insert a newline when
appending an oversize item to an empty line.

Mon Aug  8 00:51:01 EDT 1994
  Fix bug (introduced 3 Feb. 1993) that, under -i2, kept LOGICAL*2
variables from appearing in INQUIRE statements.  Under -I2, allow
LOGICAL*4 variables to appear in INQUIRE.  Fix intrinsic function
LEN so it returns a short value under -i2, a long value otherwise.
  exec.c: fix obscure memory fault possible with bizarre (and highly
erroneous) DO-loop syntax.

Fri Aug 12 10:45:57 EDT 1994
  libi77: fix glitch that kept ERR= (in list- or format-directed input)
from working after a NAMELIST READ.

Thu Aug 25 13:58:26 EDT 1994
  Suppress -s when -C is specified.

Wed Sep  7 22:13:20 EDT 1994
  libi77: typesize.c: adjust to allow types LOGICAL*1, LOGICAL*2,
INTEGER*1, and (under -DAllow_TYQUAD) INTEGER*8 in NAMELISTs.

Fri Sep 16 17:50:18 EDT 1994
  Change name adjustment for reserved words: instead of just appending
"_" (a single underscore), append "_a_" to local variable names to avoid
trouble when a common block is named a reserved word and the same
reserved word is also a local variable name.  Example:
	common /const/ a,b,c
	real const(3)
	equivalence (const(1),a)
	a = 1.234
	end
  Arrange for ichar() to treat characters as unsigned.
  libf77: s_cmp.c: treat characters as unsigned in comparisons.
These changes for unsignedness only matter for strings that contain
non-ASCII characters.  Now ichar() should always be >= 0.

Sat Sep 17 11:19:32 EDT 1994
  fc: set rc=$? before exit (to get exit code right in trap code).

Mon Sep 19 17:49:43 EDT 1994
  libf77: s_paus.c: flush stderr after PAUSE; add #ifdef MSDOS stuff.
  libi77: README: point out general need for -DMSDOS under MS-DOS.

Tue Sep 20 11:42:30 EDT 1994
  Fix bug in comparing identically named common blocks, in which
all components have the same names and types, but at least one is
dimensioned (1) and the other is not dimensioned.  Example:
	subroutine foo
	common /ab/ a
	a=1.	!!! translated correctly to ab_1.a = (float)1.;
	end
	subroutine goo
	common /ab/ a(1)
	a(1)=2.	!!! translated erroneously to ab_1.a[0] = (float)2. 
	end

Tue Sep 27 23:47:34 EDT 1994
  Fix bug introduced 16 Sept. 1994: don't add _a_ to C keywords
used as external names.  In fact, return to earlier behavior of
appending __ to C keywords unless they are used as external names,
in which case they get just one underscore appended.
  Adjust constant handling so integer and logical PARAMETERs retain
type information, particularly under -I2.  Example:
	SUBROUTINE FOO
	INTEGER I
	INTEGER*1 I1
	INTEGER*2 I2
	INTEGER*4 I4
	LOGICAL L
	LOGICAL*1 L1
	LOGICAL*2 L2
	LOGICAL*4 L4
	PARAMETER (L=.FALSE., L1=.FALSE., L2=.FALSE., L4=.FALSE.)
	PARAMETER (I=0,I1=0,I2=0,I4=0)
	CALL DUMMY(I, I1, I2, I4, L, L1, L2, L4)
	END
  f2c.1t: Change f\^2c to f2c (omit half-narrow space) in line following
".SH NAME" for benefit of systems that cannot cope with troff commands
in this context.

Wed Sep 28 12:45:19 EDT 1994
  libf77: s_cmp.c fix glitch in -DKR_headers version introduced
12 days ago.

Thu Oct  6 09:46:53 EDT 1994
  libi77: util.c: omit f__mvgbt (which is never used).
  f2c.h: change "long" to "long int" to facilitate the adjustments
by means of sed described above.  Comment out unused typedef of Long.

Fri Oct 21 18:02:24 EDT 1994
  libf77: add s_catow.c and adjust README to point out that changing
"s_cat.o" to "s_catow.o" in the makefile will permit the target of a
concatenation to appear on its right-hand side (contrary to the
Fortran 77 Standard and at the cost of some run-time efficiency).

Wed Nov  2 00:03:58 EST 1994
  Adjust -g output to contain only one #line line per statement,
inserting \ before the \n ending lines broken because of their
length [this insertion was recanted 10 Dec. 1994].  This change
accommodates an idiocy in the ANSI/ISO C standard, which leaves
undefined the behavior of #line lines that occur within the arguments
to a macro call. 

Wed Nov  2 14:44:27 EST 1994
  libi77: under compilation with -DALWAYS_FLUSH, flush buffers at
the end of each write statement, and test (via the return from
fflush) for write failures, which can be caught with an ERR=
specifier in the write statement.  This extra flushing slows
execution, but can abort execution or alter the flow of control
when a disk fills up.
  f2c/src/io.c: Add ERR= test to e_wsle invocation (end of
list-directed external output) to catch write failures when libI77
is compiled with -DALWAYS_FLUSH.

Thu Nov  3 10:59:13 EST 1994
  Fix bug in handling dimensions involving certain intrinsic
functions of constant expressions: the expressions, rather than
pointers to them, were passed.  Example:
      subroutine subtest(n,x)
      real x(2**n,n) ! pow_ii(2,n) was called; now it's pow_ii(&c__2,n) 
      x(2,2)=3.
      end

Tue Nov  8 23:56:30 EST 1994
  malloc.c: remove assumption that only malloc calls sbrk.  This
appears to make malloc.c useful on RS6000 systems.

Sun Nov 13 13:09:38 EST 1994
  Turn off constant folding of integers used in floating-point
expressions, so the assignment in
	subroutine foo(x)
	double precision x
	x = x*1000000*500000
	end
is rendered as
	*x = *x * 1000000 * 500000;
rather than as
	*x *= 1783793664;

Sat Dec 10 16:31:40 EST 1994
  Supply a better error message (than "Impossible type 14") for
	subroutine foo
	foo = 3
	end
  Under -g, convey name of included files to #line lines.
  Recant insertion of \ introduced (under -g) 2 Nov. 1994.

Thu Dec 15 14:33:55 EST 1994
  New command-line option -Idir specifies directories in which to
look for non-absolute include files (after looking in the directory
of the current input file).  There can be several -Idir options, each
specifying one directory.  All -Idir options are considered, from
left to right, until a suitably named file is found.  The -I2 and -I4
command-line options have precedence, so directories named 2 or 4
must be spelled by some circumlocation, such as -I./2 .
  f2c.ps updated to mention the new -Idir option, correct a typo,
and bring the man page at the end up to date.
  lex.c: fix bug in reading line numbers in #line lines.
  fc updated to pass -Idir options to f2c.

Thu Dec 29 09:48:03 EST 1994
  Fix bug (e.g., addressing fault) in diagnosing inconsistency in
the type of function eta in the following example:
	function foo(c1,c2)
	double complex foo,c1,c2
	double precision eta
	foo = eta(c1,c2)
	end
	function eta(c1,c2)
	double complex eta,c1,c2
	eta = c1*c2
	end

Mon Jan  2 13:27:26 EST 1995
  Retain casts for SNGL (or FLOAT) that were erroneously optimized
away.  Example:
	subroutine foo(a,b)
	double precision a,b
	a = float(b)	! now rendered as *a = (real) (*b);
	end
  Use float (rather than double) temporaries in certain expressions
of type complex.  Example: the temporary for sngl(b) in
	complex a
	double precision b
	a = sngl(b) - (3.,4.)
is now of type float.

Fri Jan  6 00:00:27 EST 1995
  Adjust intrinsic function cmplx to act as dcmplx (returning
double complex rather than complex) if either of its args is of
type double precision.  The double temporaries used prior to 2 Jan.
1995 previously gave it this same behavior.

Thu Jan 12 12:31:35 EST 1995
  Adjust -krd to use double temporaries in some calculations of
type complex.
  libf77: pow_[dhiqrz][hiq].c: adjust x**i to work on machines
that sign-extend right shifts when i is the most negative integer.

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:
