/* The "namespace tweaks" below attempt to set a friendly "compilation
environment" under popular operating systems. Default compilation
environment often means that some functions that are "extensions"
are not declared -- `strptime' is one example.
But non-default environments can expose bugs in the system header
files, crippling compilation in _very_ non-obvious ways. Because
of that, we define them only on well-tested architectures where we
know they will work. */
