Are you sure you want this left enabled?

NACK. This leads to bitrot when PCACHE_DEBUG is not defined. Also, we
typically send debug to stderr, not stdout. Instead, please follow the
lead of many other debug places, which do something similar to this (off
the top of my head, therefore untested):
#ifdef PCACHE_DEBUG
# define PCACHE_DEBUG_PRINT 1
#else
# define PCACHE_DEBUG_PRINT 0
#endif
#define DPRINTF(fmt, ...) \
do { \
if (PCACHE_DEBUG_PRINT) { \
fprintf(stderr, ... __VA_ARGS__) \
} \
} while (0)
