Revision 380238 seems to be broken at least on Linux. I believe the
intention in rw/_defs.h conditionals was to test for the definition of
the macros in the diff below since stdcxx does not define config macros
to values (0/1) as a matter of policy.
I changed all instances where the conditional tests for the macro value
and it builds:
$ svn diff
