  40  * This header file allows configuration of which output formats
  41  * get compiled into the NASM binary. You can configure by defining
  42  * various preprocessor symbols beginning with "OF_", either on the
  43  * compiler command line or at the top of this file.
  44  *
  45  * OF_ONLY                -- only include specified object formats
  46  * OF_name                -- ensure that output format 'name' is included
  47  * OF_NO_name             -- remove output format 'name'
  48  * OF_DOS                 -- ensure that 'obj', 'bin', 'win32' & 'win64' are included.
  49  * OF_UNIX                -- ensure that 'aout', 'aoutb', 'coff', 'elf32' & 'elf64' are in.
  50  * OF_OTHERS              -- ensure that 'bin', 'as86', 'rdf' 'macho32' & 'macho64' are in.
  51  * OF_ALL                 -- ensure that all formats are included.
  52  *                           note that this doesn't include 'dbg', which is
  53  *                           only really useful if you're doing development
  54  *                           work on NASM. Define OF_DBG if you want this.
  55  *
  56  * OF_DEFAULT=of_name     -- ensure that 'name' is the default format.
  57  *
  58  * eg: -DOF_UNIX -DOF_ELF32 -DOF_DEFAULT=of_elf32 would be a suitable config
  59  * for an average linux system.
  60  *
  61  * Default config = -DOF_ALL -DOF_DEFAULT=of_bin
  62  *
  63  * You probably only want to set these options while compiling 'nasm.c'. */
