Replaced makefile with a BSD Makefile. Moved the unformatted man page

to f2c.1. Removed an automatically generated file and a checksum file.

-     NAME
-	  f2c -	Convert	Fortran	77 to C	or C++
-
-     SYNOPSIS
-	  f2c [	option ... ] file ...
-
-     DESCRIPTION
-	  F2c converts Fortran 77 source code in files with names end-
-	  ing in `.f' or `.F' to C (or C++) source files in the	cur-
-	  rent directory, with `.c' substituted	for the	final `.f' or
-	  `.F'.	 If no Fortran files are named,	f2c reads Fortran from
-	  standard input and writes C on standard output.  File	names
-	  that end with	`.p' or	`.P' are taken to be prototype files,
-	  as produced by option	`-P', and are read first.
-
-	  The following	options	have the same meaning as in f77(1).
-
-	  -C   Compile code to check that subscripts are within
-	       declared	array bounds.
-
-	  -I2  Render INTEGER and LOGICAL as short, INTEGER*4 as long
-	       int.  Assume the	default	libF77 and libI77:  allow only
-	       INTEGER*4 (and no LOGICAL) variables in INQUIREs.
-	       Option `-I4' confirms the default rendering of INTEGER
-	       as long int.
-
-	  -onetrip
-	       Compile DO loops	that are performed at least once if
-	       reached.	 (Fortran 77 DO	loops are not performed	at all
-	       if the upper limit is smaller than the lower limit.)
-
-	  -U   Honor the case of variable and external names.  Fortran
-	       keywords	must be	in lower case.
-
-	  -u   Make the	default	type of	a variable `undefined' rather
-	       than using the default Fortran rules.
-
-	  -w   Suppress	all warning messages.  If the option is
-	       `-w66', only Fortran 66 compatibility warnings are sup-
-	       pressed.
-
-	  The following	options	are peculiar to	f2c.
-
-	  -A   Produce ANSI C.	Default	is old-style C.
-
-	  -a   Make local variables automatic rather than static
-	       unless they appear in a DATA, EQUIVALENCE, NAMELIST, or
-	       SAVE statement.
-
-	  -C++ Output C++ code.
-
-	  -c   Include original	Fortran	source as comments.
-
-     Page 1			   Local	      (printed 2/2/93)
-
-     F2C(1)							F2C(1)
-
-	  -E   Declare uninitialized COMMON to be Extern (overridably
-	       defined in f2c.h	as extern).
-
-	  -ec  Place uninitialized COMMON blocks in separate files:
-	       COMMON /ABC/ appears in file abc_com.c.	Option `-e1c'
-	       bundles the separate files into the output file,	with
-	       comments	that give an unbundling	sed(1) script.
-
-	  -ext Complain	about f77(1) extensions.
-
-	  -f   Assume free-format input: accept	text after column 72
-	       and do not pad fixed-format lines shorter than 72 char-
-	       acters with blanks.
-
-	  -72  Treat text appearing after column 72 as an error.
-
-	  -g   Include original	Fortran	line numbers in	#line lines.
-
-	  -h   Emulate Fortran 66's treatment of Hollerith: try	to
-	       align character strings on word (or, if the option is
-	       `-hd', on double-word) boundaries.
-
-	  -i2  Similar to -I2, but assume a modified libF77 and	libI77
-	       (compiled with -Df2c_i2), so INTEGER and	LOGICAL	vari-
-	       ables may be assigned by	INQUIRE	and array lengths are
-	       stored in short ints.
-
-	  -kr  Use temporary values to enforce Fortran expression
-	       evaluation where	K&R (first edition) parenthesization
-	       rules allow rearrangement.  If the option is `-krd',
-	       use double precision temporaries	even for single-
-	       precision operands.
-
-	  -P   Write a file.P of ANSI (or C++) prototypes for defini-
-	       tions in	each input file.f or file.F.  When reading
-	       Fortran from standard input, write prototypes at	the
-	       beginning of standard output.  Option -Ps implies -P
-	       and gives exit status 4 if rerunning f2c	may change
-	       prototypes or declarations.
-
-	  -p   Supply preprocessor definitions to make common-block
-	       members look like local variables.
-
-	  -R   Do not promote REAL functions and operations to DOUBLE
-	       PRECISION.  Option `-!R'	confirms the default, which
-	       imitates	f77.
-
-	  -r   Cast values of REAL functions (including	intrinsics) to
-	       REAL.
-
-	  -r8  Promote REAL to DOUBLE PRECISION, COMPLEX to DOUBLE
-	       COMPLEX.
-

-
-     F2C(1)							F2C(1)
-
-	  -s   Preserve	multidimensional subscripts.
-
-	  -Tdir
-	       Put temporary files in directory	dir.
-
-	  -w8  Suppress	warnings when COMMON or	EQUIVALENCE forces
-	       odd-word	alignment of doubles.
-
-	  -Wn  Assume n	characters/word	(default 4) when initializing
-	       numeric variables with character	data.
-
-	  -z   Do not implicitly recognize DOUBLE COMPLEX.
-
-	  -!bs Do not recognize	backslash escapes (\", \', \0, \\, \b,
-	       \f, \n, \r, \t, \v) in character	strings.
-
-	  -!c  Inhibit C output, but produce -P	output.
-
-	  -!I  Reject include statements.
-
-	  -!i8 Disallow	INTEGER*8.
-
-	  -!it Don't infer types of untyped EXTERNAL procedures	from
-	       use as parameters to previously defined or prototyped
-	       procedures.
-
-	  -!P  Do not attempt to infer ANSI or C++ prototypes from
-	       usage.
-
-	  The resulting	C invokes the support routines of f77; object
-	  code should be loaded	by f77 or with ld(1) or	cc(1) options
-	  -lF77	-lI77 -lm.  Calling conventions	are those of f77: see
