# If you specify "-DHAS_NDBM_H", ndbm calls will be used instead
# of dbm ones, and the feature will be activated of Cnews log processing
# to add entries to SEEN-BY if echo message is exported to several FTN
# nodes by Cnews mechanism. This works with INN too.

# If you specify "-DHAS_STATFS" or "-DHAS_STATVFS", statfs() (or statvfs()
# respectivly) call will be used to check available disk space. For statfs()
# call, you must also specify which .h file to use: "-DSTATFS_IN_VFS_H" or 
# "-DSTATFS_IN_STATFS_H" or "-DSTATFS_IN_STATVFS_H"  or "-DSTATFS_IN_MOUNT_H". 
# For statvfs() call, statvfs.h is included.

# define -DSCO_STYLE_STATFS if your statfs() call requires 4 arguments.

# If you specify "-DHAS_SETSID", setsid() call is used to detach from the
# control terminal. Otherwise setpgrp() call is used, and in this case you
# may specify "-DBSD_SETPGRP" to use BSD-style call.  Used in ifcico only.

# If you specify "-DDONT_HAVE_TM_GMTOFF", timezone offset will be calculated
# from the difference between the results of localtime() and gmtime() calls
# instead of using tm_gmtoff field of struct tm.

# If you specify "-DDONT_HAVE_GETOPT", local definitions for getopt will
# be used (but not the function itself)

# For ifcico, you must specify -DHAS_TERMIOS_H (preffered), -DHAS_TERMIO_H
# or -DHAS_SGTTY_H to use POSIX-y, SysV-ish of BSD-ish terminal control.

# in SVR4 you should specify -DHAS_DIAL (and maybe -DHAS_DIAL_H) to use
# dial() library function instead of regular open().  Lock files are
# not used in this case.

# for uucp lock files, you must specify either -DASCII_LOCKFILES or
# -DBINARY_LOCKFILES

# define -DHAS_FSYNC if there is a fsync() system call (to update .flo
# files)

# define -DPARANOID if you want iftoss to deny packets with wrong password.

# define -DRELAXED if you want iftoss to accept packets that are not
# addressed to your node.

# define -DFORCEINTL if you want ifmail to create ^aINTL even if this is
# not an inter-zone netmail.

# define -DNEED_UUCPFROM if your MTA needs a uucp "From" line in mail.

# define -DHAS_TCP if you want ifmail to be able to originate outgoing
# connections over TCP/IP (socket library needed)

# define -DHAS_TERM if you want ifmail to be able to originate outgoing
# connections over TERM (TCP "extention", client.a needed)

# define -DHAS_REGEX_H or -DHAS_LIBGEN_H if you have either of these
# header files for regular expression handlers.

# define -DHAS_SYSLOG to use syslog() instead of logging to files.
# Files are necessary anyway, external programs' stdout and stderr
# are redirected there.

# define -DNEED_BSY if you want ifpack and ifcico to create .bsy
# files preventing simultaneous processing of the same node.

# define -DNEED_FORK if your system is uncapable of getting rid of the
# control terminal unless you are running not as a group leader.

# define -DREGEX_NEED_CARET if your re_comp/re_exec require that the
# mask starts with a '^' to match the beginning of the string.

# as of June 1994, FreeBSD has a nasty bug in the kernel lseek() code:
# if you make lseek() to a point before the start of the file, it
# succeeds and the writing point becomes negative.  Fortunately, 
# subsequent write()s fail :-).  To overwork this, define 
# -DNEGATIVE_SEEK_BUG, this will add an extra fseek() to restore
# zero writing point where necessary.

# define -DNEED_TRAP if you want debugging information when the programs
# are aborted with segmentation fault etc.  Currently tested and works 
# only with Linux, and only with newer kernels (1.1.20+)

# define -DSLAVE_SENDS_NAK_TOO if you have problems answering incoming
# EMSI sessions originated by FrontDoor.  FrontDoor does not follow
# EMSI specifications when originating calls, this is a workaround.

# define -DDONT_HAVE_DIRENT if there is no working opendir()/readdir()
# etc. in your libc.  You will aso need to add "dirent.o" to the NEEDED
# (see below).

# On ISC, if you are suing gcc, you can run into a trouble with sscanf()

# string is a constant segfaults unless you specify "-fwritable-strings"
# to gcc.  I would say that this is a bug in ISC libc.  If nessecary,
# add this to the defines above.  If you have ISC version 4.0 or later,
