[boost] Metrowerks regression on Date-Time library

From: Beman Dawes (bdawes_at_[hidden])

Sometime between October 17th and 20th the Date-Time library started 
failing for the Metrowerks compiler. See error message below. Note that the 
supposedly undefined identifier doesn't appear in the function (or even the 
file).

There were changes made to the library on the 19th, but they seem to be 
unrelated. The particular file the error is reported in did not change.

Jeff Garland and I have independently tried to figure out what the problem 
is, but without luck. Without at least some idea of what the problem is, a 
workaround isn't possible.

Unless someone else comes up with a workaround, we don't seem to have much 
choice but to wait for Metrowerk's next compiler version and hope that 
fixes the problem. Thus the pending Boost release will have a regression 
for the Date-Time library.
