No need to manually include <sys/signal.h>, <signal.h> does that. This
was probably done because -D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=700
would cause __BSD_VISIBLE to be undefined which in turn would prevent
SIGWINCH from being defined.
-D_XOPEN_SOURCE_EXTENDED is needed, otherwise the compiler will warn
about implicitly defined addnwstr(3).
When unhiding ${CC} in Makefile, remove the corresponding @echo line
to avoid duplicate output such as
CC dvtm.c
cc -c -O2 -pipe ... dvtm.c
