Yes, of course, but a bit later. Currently changes are in progress, 
preparing to putenv() rewriting.

Unlike portable soft like gcc, cvs, etc. FreeBSD have a bad habbit 
considering putenv() arg as safe to pass and forget (because 
putenv() was incorrecly implemented via setenv(), which copy the arg), 
there still a lot of places to fix, almost every putenv() usage in FreeBSD 
is unportable... :(
