--- Comment #2 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com> ---
I don't see why this is needed: when --enable-lirc is passed, and the lirc
library is found, the configure script defines HAVE_LIRC:

AC_ARG_ENABLE([lirc],
  [AS_HELP_STRING([--disable-lirc],
  [disable lirc support (default is enabled)])],
  [AC_MSG_RESULT("Lirc disabled")],
  [AC_DEFINE([HAVE_LIRC], [1], ["Lirc enabled"])])

And then, when HAVE_LIRC is defined, HAS_LIRC gets defined by xbmc/system.h:

#ifdef HAVE_LIRC
#define HAS_LIRC
#endif

And HAS_LIRC is the define being tested at the code you point to.
