    NOTE: See the BUGS file for a Linux issue when compiling calc
    with -O (or -O2 or -O3) AND with -g (or -g3) AND with readline.

+    Removed an obsolete reference to TOPDIR.  This was fixed thanks to
+    a bug report by Clifford Kite <kite_public1 at ev1 dot net>.
+
+    Fixed calc man page so that is refers to -f instead of the old -S flag.
+    Fixed thanks to Clifford Kite <kite_public1 at ev1 dot net> for
+    point this out.
+
+    All for loops end with /dev/null to avoid any problems related
+    to systems that cannot grok empty for loops.
+
+    Changed the libcalc functions creal and cimag to c_real and c_imag
+    to about conflicts with new libc such as those used by gcc v3.
+    Thanks Eli Zaretskii <eliz at is dot elta dot co dot il> and
+    Martin Buck <m at rtin-buck dot de> for alerting us to this conflict.
+
+    The Makefile no longer hard code's /usr/include.  Instead it uses
+    the ${INCDIR} Makefile variable.  Thanks goes to Eli Zaretskii
+    <eliz at is dot elta dot co dot il> for pointing out this inconsistency.
+
+    Added mods to support compilation under DJGPP.  DJGPP runs on 386
+    and newer PCs running DOS or dos-compatible operating systems.
+    See http://www.delorie.com/djgpp/.  Thanks goes to Eli Zaretskii
+    <eliz at is dot elta dot co dot il> for sending in these mods.
+
+    Updated README.WINDOWS to include information on building with DJGPP.
+
+    The pld folks are building RPMs based on our calc distrbutions.
+    See:  ftp://ftp.pld.org.pl/dists/ra/PLD/i686/PLD/RPMS or
+    http://ftp.pld.org.pl/dists/ra/PLD/i686/PLD/RPMS more information.
+    We appreciate their work in this regard.  In the next release, we
+    plan to also build and release our own RPMs based on their efforts.

+There is a different approach to the Cygwin approach above
+----------------------------------------------------------
+
+You might want to try using the DJGPP system to compile calc.  See:
+
+	http://www.delorie.com/djgpp/
+
+for DJGPP details and availability.
+
+To compile with DJGPP, one needs to select a number of Makefile
+variable changes.  Eli Zaretskii <eliz at is dot elta dot co dot il>
+recommends the following settings:
+
+	TERMCONTROL= -DUSE_TERMIOS
+	BYTE_ORDER= -DLITTLE_ENDIAN
+	LONG_BITS= 32
+	LONGLONG_BITS= 64
+	HAVE_FPOS_POS= -DHAVE_NO_FPOS_POS
+	FPOS_BITS= 32
+	OFF_T_BITS= 32
+	DEV_BITS= 32
+	INODE_BITS= 32
+	HAVE_USTAT= -DHAVE_NO_USTAT
+	HAVE_GETSID= -DHAVE_NO_GETSID
+	HAVE_GETPGID= -DHAVE_NO_GETPGID
+	HAVE_GETTIME= -DHAVE_NO_GETTIME
+	HAVE_GETPRID= -DHAVE_NO_GETPRID
+	HAVE_URANDOM_H= NO
+	ALIGN32= -UMUST_ALIGN32
+	HAVE_MALLOC_H= YES
+	HAVE_STDLIB_H= YES
+	HAVE_STRING_H= YES
+	HAVE_TIMES_H= NO
+	HAVE_SYS_TIMES_H= YES
+	HAVE_TIME_H= YES
+	HAVE_SYS_TIME_H= YES
+	HAVE_UNISTD_H= YES
+	BINDIR= /dev/env/DJDIR/bin
+	SHAREDIR= /dev/env/DJDIR/share
+	INCDIR= /dev/env/DJDIR/include
+	LIBDIR= /dev/env/DJDIR/lib
+	MANDIR= /dev/env/DJDIR/man/man1
+	CATDIR= /dev/env/DJDIR/man/cat1
+	NROFF= groff
+	CALCPATH= .;./cal;~/.cal;${CSHAREDIR};${CUSTOMLIBDIR}
+	CALCRC= ${CSHAREDIR}/startup;~/.calcrc;./.calcinit
+	CALCPAGER= less.exe -ci
+	DEBUG= -O2 -gstabs+
+
+The 'Linux set' or 'gcc set' (see the Select your compiler type section)
+should work for DJGPP systems if you set the above Makefile variables.
+
+Look for Makefile comments of the form:
+
+	# Select ...something... for DJGPP.
+
+Follow those recommendations.  In cases where they conflict with
+the above Makefile list, follow the recommendation in the Makefile.
