Clean up: the use of identifiers called "access" and "daemon" shadow
function declarations in unistd.h. Seen with "-Wextra -pedantic".
tcpwrapper.c: In function ‘haccess_add’:
tcpwrapper.c:112: warning: declaration of ‘access’ shadows a global
declaration
/usr/include/unistd.h:288: warning: shadowed declaration is here
tcpwrapper.c: In function ‘good_client’:
tcpwrapper.c:161: warning: declaration of ‘daemon’ shadows a global
declaration
/usr/include/unistd.h:953: warning: shadowed declaration is here
tcpwrapper.c: In function ‘check_default’:
tcpwrapper.c:212: warning: declaration of ‘daemon’ shadows a global
declaration
/usr/include/unistd.h:953: warning: shadowed declaration is here
good_client() is used only in support/misc/tcpwrapper.c, so make it
static (and update its prototype to c99 standard form).
