On macOS, both <unistd.h> and <string.h> declar swab(), which may result in a conflicting types error due to differences in declaration qualifiers. According to POSIX, swab() is officially declared in <unistd.h>. macOS also declares it in <string.h> for compatibility, but without proper include guards. This PR resolves the issue by: - Reordering includes in util.h to ensure <unistd.h> appears before <string.h> - Removing a redundant include in vmstate.c Tested on macOS 12.1
