+If your compiler does not recognize ANSI C headers,
+compile with KR_headers defined:  either add -DKR_headers
+to the definition of CFLAGS in the makefile, or insert
+
+#define KR_headers
+
+at the top of f2c.h , cabs.c , main.c , and sig_die.c .
+
+Under MS-DOS, compile s_paus.c with -DMSDOS.
+
+If you have a really ancient K&R C compiler that does not understand
+void, add -Dvoid=int to the definition of CFLAGS in the makefile.
+
+If you use a C++ compiler, first create a local f2c.h by appending
+f2ch.add to the usual f2c.h, e.g., by issuing the command
+	make f2c.h
+which assumes f2c.h is installed in /usr/include .
+
+If your system lacks onexit() and you are not using an ANSI C
+compiler, then you should compile main.c, s_paus.c, s_stop.c, and
+sig_die.c with NO_ONEXIT defined.  See the comments about onexit in
+the makefile.
+
+If your system has a double drem() function such that drem(a,b)
+is the IEEE remainder function (with double a, b), then you may
+wish to compile r_mod.c and d_mod.c with IEEE_drem defined.
+On some systems, you may also need to compile with -Ddrem=remainder .
+
+To check for transmission errors, issue the command
+	make check
+This assumes you have the xsum program whose source, xsum.c,
+is distributed as part of "all from f2c/src".  If you do not
+have xsum, you can obtain xsum.c by sending the following E-mail
+message to netlib@netlib.bell-labs.com
+	send xsum.c from f2c/src
+
+The makefile assumes you have installed f2c.h in a standard
+place (and does not cause recompilation when f2c.h is changed);
+f2c.h comes with "all from f2c" (the source for f2c) and is
+available separately ("f2c.h from f2c").
+
+Most of the routines in libF77 are support routines for Fortran
+intrinsic functions or for operations that f2c chooses not
+to do "in line".  There are a few exceptions, summarized below --
+functions and subroutines that appear to your program as ordinary
+external Fortran routines.
+
+1.	CALL ABORT prints a message and causes a core dump.
+
+2.	ERF(r) and DERF(d) and the REAL and DOUBLE PRECISION
+	error functions (with x REAL and d DOUBLE PRECISION);
+	DERF must be declared DOUBLE PRECISION in your program.
+	Both ERF and DERF assume your C library provides the
+	underlying erf() function (which not all systems do).
+
+3.	ERFC(r) and DERFC(d) are the complementary error functions:
+	ERFC(r) = 1 - ERF(r) and DERFC(d) = 1.d0 - DERFC(d)
+	(except that their results may be more accurate than
+	explicitly evaluating the above formulae would give).
+	Again, ERFC and r are REAL, and DERFC and d are DOUBLE
+	PRECISION (and must be declared as such in your program),
+	and ERFC and DERFC rely on your system's erfc().
+
+4.	CALL GETARG(n,s), where n is an INTEGER and s is a CHARACTER
+	variable, sets s to the n-th command-line argument (or to
+	all blanks if there are fewer than n command-line arguments);
+	CALL GETARG(0,s) sets s to the name of the program (on systems
+	that support this feature).  See IARGC below.
+
+5.	CALL GETENV(name, value), where name and value are of type
+	CHARACTER, sets value to the environment value, $name, of
+	name (or to blanks if $name has not been set).
+
+6.	NARGS = IARGC() sets NARGS to the number of command-line
+	arguments (an INTEGER value).
+
+7.	CALL SIGNAL(n,func), where n is an INTEGER and func is an
+	EXTERNAL procedure, arranges for func to be invoked when
+	signal n occurs (on systems where this makes sense).
+
+8.	CALL SYSTEM(cmd), where cmd is of type CHARACTER, passes
+	cmd to the system's command processor (on systems where
+	this can be done).
+
+The makefile does not attempt to compile pow_qq.c, qbitbits.c,
+and qbitshft.c, which are meant for use with INTEGER*8.  To use
+INTEGER*8, you must modify f2c.h to declare longint and ulongint
+appropriately; then add pow_qq.o to the POW = line in the makefile,
+and add " qbitbits.o qbitshft.o" to the makefile's F90BIT = line.
+
+Following Fortran 90, s_cat.c and s_copy.c allow the target of a
+(character string) assignment to be appear on its right-hand, at
+the cost of some extra overhead for all run-time concatenations.
+If you prefer the  extra efficiency that comes with the Fortran 77
+requirement that the left-hand side of a character assignment not
+be involved in the right-hand side, compile s_cat.c and s_copy.c
+with -DNO_OVERWRITE .
+
+If your system lacks a ranlib command, you don't need it.
+Either comment out the makefile's ranlib invocation, or install
+a harmless "ranlib" command somewhere in your PATH, such as the
+one-line shell script
+
+	exit 0
+
+or (on some systems)
+
+	exec /usr/bin/ar lts $1 >/dev/null
