+
+# Porting considerations:
+#
+#    For System V Unix machines, add -DUSG to CFLAGS (if it's not
+#         automatically defined)
+#    For Vax/VMS, add "-DVMS -DUSG" to CFLAGS.
+#    For MS-DOS, add "-DMS_DOS -DUSG" to CFLAGS.  Create \tmp if not present.
+#         You will also want to rename flex.skel to something with a three
+#         character extension, change SKELETON_FILE below appropriately,
+#	  See MSDOS.notes for more info.
+#    For Amiga, add "-DAMIGA -DUSG" to CFLAGS.
+#    For SCO Unix, add "-DSCO_UNIX" to CFLAGS.
+#
+#    For C compilers which don't know about "void", add -Dvoid=int to CFLAGS.
+#
+#    If your C compiler is ANSI standard but does not include the <stdlib.h>
+#    header file (some installations of gcc have this problem), then add
+#    -DDONT_HAVE_STDLIB_H to CFLAGS.
+#
+# By default, flex will be configured to generate 8-bit scanners only
+# if the -8 flag is given.  If you want it to always generate 8-bit
+# scanners, add "-DDEFAULT_CSIZE=256" to CFLAGS.  Note that doing
+# so will double the size of all uncompressed scanners.
+# 
+# If on your system you have trouble building flex due to 8-bit
+# character problems, remove the -8 from FLEX_FLAGS and the
+# "#define FLEX_8_BIT_CHARS" from the beginning of flexdef.h.
+
+
+# the first time around use "make first_flex"
+
+
+# Installation targeting.  Files will be installed under the tree rooted
+# at DESTDIR.  User commands will be installed in BINDIR, library files
+# in LIBDIR (which will be created if necessary), auxiliary files in
+# AUXDIR, manual pages will be installed in MANDIR with extension MANEXT.
+# Raw, unformatted troff source will be installed if INSTALLMAN=man, nroff
+# preformatted versions will be installed if INSTALLMAN=cat.
