Not in that form, that I recall, but there were a variety of suggestions
for ways to "standardize" such parameterization of the environment.
Basically the use of macros for denoting specific operating systems and
hardware doesn't seem to be fine-grained enough.  People who specialize
in portable applications usually have their own methods for dealing with
such environmental variation, and it doesn't seem that one particular
method stands out as one that should be "legislated".  The emphasis was
on providing a sufficiently useful standard environment that there would
be little need for conditionalizing code based on such factors.
