Sometimes.  (Ab)using enums for bitmasks or other things that get
arithmetic applied to them (eg, O_EXEC, to pick a recently-discussed
example) is, IMO, broken - besides being unwarranted chumminess with
the compiler, they don't help debugging; even a debugger that can turn
64 into O_ASYNC won't be able to turn 3589 back into

Okay, what's the static inline version of log() here?

#define log(msg) log_(__FILE__,__LINE__,(msg))
extern void log_(const char *, int, const char *);
