Just use double parentheses:

  log_msg_if_debugflag(DEB_NOISE, ("%s: %d invalid", p, i));

#define log_msg_if_debugflag(flag,args) if (debugflags & flag) printf args

[You probably want a do-while0 around that to avoid spurious matching of
"else" statements, thus:]

#define log_msg_if_debugflag(flag,args) do { \
    if (debugflags & flag) printf args; \
  } while (0)
