I  hate replying to my own posts, but perhaps this will help some one 
else in their debugging efforts as well.  While compiling the mimedefang 
package, I have identified the following:

mimedefang.c: In function 'rcptto':
mimedefang.c:967: warning: pointer targets in passing argument 2 of 
'writestr' d
iffer in signedness
mimedefang.c:969: warning: pointer targets in passing argument 2 of 
'writestr' d
iffer in signedness
mimedefang.c:971: warning: pointer targets in passing argument 2 of 
'writestr' d
iffer in signedness
mimedefang.c:973: warning: pointer targets in passing argument 2 of 
'writestr' d
iffer in signedness
mimedefang.c:975: warning: pointer targets in passing argument 2 of 
'writestr' d
iffer in signedness
mimedefang.c: In function 'header':
mimedefang.c:1030: warning: pointer targets in passing argument 2 of 
'writestr'

There are many of these errors, now to track the source of this down.
