^This will likely introduce a "cast to pointer from integer of different
size" warning on LP64 targets.
syslog_dummy = fopen("/dev/null", "w");
would be, at the cost of one more open fd, a "nice" solution,
since syslog_dummy is guaranteed to be unique, without making
any assumptions about any magic value(s) being unused.
That, or turn the assumptive macro into
#define SYSLOG_DUMMY ((FILE *)(intptr_t)-1)
