 I had originally worked around this problem in some other package that 
 used recursive configure scripts by doing something like:
 
 CONFIGURE_ENV+=	CPPFLAGS="${CPPFLAGS:M*}"
 
 which seemed to strip out extra whitespace at the front and in-between 
 options passed via CPPFLAGS.  I think in the new way that variables are 
 being passed to configure and make via ALL_ENV, the same workaround 
 would look like:
 
 ALL_ENV+=	CPPFLAGS=${CPPFLAGS:M*:Q}
 
 Todd, I'm not completely up-to-date on the changes that you've been 
 making over the past few months to have variables are set and passed. 
 Could you verify that this is conceptually and syntactically correct?
 
 	Thanks,
