*  NUM_DEF -- Standalone stub for the Starlink NUM "definitions" include file.
*
*  In the real Starlink NUM package, NUM_DEF contains Fortran macros
*  for the numeric conversion routines.
*
*  For standalone builds those same routines are compiled as ordinary C
*  functions in num_standalone.c and linked into libstar_compat, so this
*  file is intentionally empty: the functions are already declared EXTERNAL
*  via NUM_DEC and resolved at link time.
