/**
** 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-
** build 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
**
