Could someone here remark on the accuracy of the submitters claim?
Basically, the submitter believes that if one defines the '.POSIX'
target in his local makefile, he should get the desired
behavior. However, FreeBSD is currently set up such that if '.POSIX'
is the first target in sys.mk, one gets the POSIX behavior.

".POSIX The application shall ensure that this special target is specified
without prerequisites or commands. If it appears as the first
non-comment line in the makefile, make shall process the makefile
as specified by this section; otherwise, the behavior of make is
unspecified."
Later on it mentions the list of variables and their values.
# All of this does work when the
# ".POSIX" target is set in sys.mk. In exactly which makefile is the
# ".POSIX" target supposed to work?
The application programmer's. See the example in the PR.
# If it is in the local one, this is a
# real problem. Goes against the whole way makefiles are processed.
I'm not sure what you mean with "local makefile".

Jens
