clang on native Windows gives me this warning:
gllib\bcopy.c(27,1): warning: no previous prototype for function 'bcopy'
[-Wmissing-prototypes]
The normal way to fix this would be to add a '#include <strings.h>' in
lib/bcopy.c. But our <strings.h> does not even provide a declaration of
this function! It relies on AC_REPLACE_FUNCS and a K&R C compiler.
Instead of putting effort into this outdated module, it is better to just
mark it as deprecated.
