  11  * This header file allows configuration of which output formats
  12  * get compiled into the NASM binary. You can configure by defining
  13  * various preprocessor symbols beginning with "OF_", either on the
  14  * compiler command line or at the top of this file.
  15  *
  16  * OF_ONLY                -- only include specified object formats
  17  * OF_name                -- ensure that output format 'name' is included
  18  * OF_NO_name             -- remove output format 'name'
  19  * OF_DOS                 -- ensure that 'obj', 'bin' & 'win32' are included.
  20  * OF_UNIX                -- ensure that 'aout', 'aoutb', 'coff', 'elf' are in.
  21  * OF_OTHERS              -- ensure that 'bin', 'as86' & 'rdf' are in.
  22  * OF_ALL                 -- ensure that all formats are included.
  23  *
  24  * OF_DEFAULT=of_name     -- ensure that 'name' is the default format.
  25  *
  26  * eg: -DOF_UNIX -DOF_ELF -DOF_DEFAULT=of_elf would be a suitable config
  27  * for an average linux system.
  28  *
  29  * Default config = -DOF_ALL -DOF_DEFAULT=of_bin
  30  *
  31  * You probably only want to set these options while compiling 'nasm.c'. */
