My experience is that everyone who's reported a bug against SunOS
4.1.x for several years, is either (1) doing it only because they're
worried we might still want to be portable to SunOS 4.1.x, or (2)
maintaining a computer museum.  Neither of these cases are worth
worrying about.

Not these days, no.  However it is possible that a freestanding
environment would have neither math.h nor the math functions.  PalmOS
is one fairly-contemporary example.  It's less likely for string.h to
be missing (PalmOS has it, albeit in a shim mode if memory serves).
