POSIX doesn't require strcasecmp or strncasecmp to be visible in
<string.h> (they are only mandatory in <strings.h>).  But it also
permits <string.h> to declare anything it wants in the str* namespace,
so this is still standards compliant, and closer to what lazy
programmers have gotten used to with glibc.
