  39  **  This template file is used while building the GNAT runtime library to
  40  **  generate package System.OS_Constants (s-oscons.ads).
  41  **
  42  **  The generation process is:
  43  **  1. the platform-independent extraction tool xoscons is built with the
  44  **     base native compiler
  45  **  2. this template is processed by the cross C compiler to produce
  46  **     a list of constant values
  47  **  3. the comments in this template and the list of values are processed
  48  **     by xoscons to generate s-oscons.ads.
  49  **
  50  **  Any comment occurring in this file whose start and end markers are on
  51  **  a line by themselves (see above) is copied verbatim to s-oscons.ads.
  52  **  All other comments are ignored. Note that the build process first passes
  53  **  this file through the C preprocessor, so comments that occur in a section
  54  **  that is conditioned by a #if directive will be copied to the output only
  55  **  when it applies.
  56  **
  57  **  Two methods are supported to generate the list of constant values,
  58  **  s-oscons-tmpl.s.
  59  **
  60  **  The default one assumes that the template can be compiled by the newly-
  61  **  built cross compiler. It uses markup produced in the (pseudo-)assembly
  62  **  listing:
  63  **
  64  **     xgcc -DTARGET=\"$target\" -C -E s-oscons-tmplt.c > s-oscons-tmplt.i
  65  **     xgcc -S s-oscons-tmplt.i
  66  **     xoscons
  67  **
  68  **  Alternatively, if s-oscons-tmplt.c must be compiled with a proprietary
  69  **  compiler (e.g. the native DEC CC on OpenVMS), the NATIVE macro should
  70  **  be defined, and the resulting program executed:
  71  **
  72  **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE)
  73  **      /PREPROCESS_ONLY /COMMENTS=AS_IS s-oscons-tmplt
  74  **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE) s-oscons-tmplt
  75  **  $ LINK s-oscons-tmplt
  76  **  $ DEFINE/USER SYS$OUTPUT s-oscons-tmplt.s
  77  **  $ RUN s-oscons-tmplt
  78  **  $ RUN xoscons
