/**
 **  This template file is used while building the GNAT runtime library to
 **  generate package System.OS_Constants (s-oscons.ads).
 **
 **  The generation process is:
 **  1. the platform-independent extraction tool xoscons is built with the
 **     base native compiler
 **  2. this template is processed by the cross C compiler to produce
 **     a list of constant values
 **  3. the comments in this template and the list of values are processed
 **     by xoscons to generate s-oscons.ads.
 **
 **  Any comment occurring in this file whose start and end markers are on
 **  a line by themselves (see above) is copied verbatim to s-oscons.ads.
 **  All other comments are ignored. Note that the build process first passes
 **  this file through the C preprocessor, so comments that occur in a section
 **  that is conditioned by a #if directive will be copied to the output only
 **  when it applies.
 **
 **  Two methods are supported to generate the list of constant values,
 **  s-oscons-tmpl.s.
 **
 **  The default one assumes that the template can be compiled by the newly-
 **  built cross compiler. It uses markup produced in the (pseudo-)assembly
 **  listing:
 **
 **     xgcc -DTARGET=\"$target\" -C -E s-oscons-tmplt.c > s-oscons-tmplt.i
 **     xgcc -S s-oscons-tmplt.i
 **     xoscons
 **
 **  Alternatively, if s-oscons-tmplt.c must be compiled with a proprietary
 **  compiler (e.g. the native DEC CC on OpenVMS), the NATIVE macro should
 **  be defined, and the resulting program executed:
 **
 **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE)
 **      /PREPROCESS_ONLY /COMMENTS=AS_IS s-oscons-tmplt
 **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE) s-oscons-tmplt
 **  $ LINK s-oscons-tmplt
 **  $ DEFINE/USER SYS$OUTPUT s-oscons-tmplt.s
 **  $ RUN s-oscons-tmplt
 **  $ RUN xoscons
