dovecot - Aug 2006 - Issue building rc6 on Mac OS X (quota)

I haven't had time to put together a patch, but quota-fs.c fails to  
compile on Mac OS X.

Any chance we could get a configuration switch that says "--without- 
quota"? I've resolved the problem temporarily by forcing  
HAVE_FS_QUOTA to undef in quota-fs.h.
