[Mimedefang] Problems compiling on BSD/OS 4.0

[Chris Wargaski]

Hello--

	I am attempting to compile MIMEdefang-2.21 on BSD/OS 4.0. I have run into 
no other
problems with perl-5.8 or other modules, yet.

	Here is the make output:

mchenry: {25} % make
gcc -g 
-O2  -D_POSIX_PTHREAD_SEMANTICS  -DPERL_PATH=\"/usr/bin/perl\"  -DMIMEDEFAN
G_PL=\"/usr/local/bin/mimedefang.pl\"  -DRM=\"/bin/rm\"  -DVERSION=\"2.21\" 
  -DSPO
OLDIR=\"/var/spool/MIMEDefang\"  -DQDIR=\"/var/spool/MIMEDefang\" 
-DCONFDIR=\"/et
c/mail\"  -c -o mimedefang.o mimedefang.c

	[ snip ]

gcc -g -O2  -o mimedefang mimedefang.o drop_privs.o utils.o rm_r.o 
/usr/local/lib/
libmilter.a -lresolv
rm_r.o: In function `rm_r':
/home/cjw/src/modules/mimedefang-2.21/rm_r.c:67: undefined reference to 
`readdir_r
'
*** Error code 1

Stop.

	I do see a reference to the system call readdir() in the OS, but not 
readdir_r(). It appears
  that this has not been implemented in 4.0. Can anyone suggest a 
work-around or have a
homemade reddir_r()?
