Hmm.  From the make(1) manpage:

: The four different classes of variables (in order of increasing prece-
: dence) are:
: 
: Environment variables
:      Variables defined as part of make's environment.
: 
: Global variables
:      Variables defined in the makefile or in included makefiles.
: 
: Command line variables
:      Variables defined as part of the command line.
: 
: Local variables
:      Variables that are defined specific to a certain target.  The
:      seven local variables are as follows:

Are you telling me that setting CFLAGS in the ENVIRONMENT causes
this strange behavior?  (I cannot reproduce it here, because
environment variables are of a lower precedence than globals.)

Are you sure you weren't running make(1) with the -e option?
(I can reproduce this with this option, as it causes environment
variables to take higher precedence than globals.)
