#include <string.h>
/* objlist_file_supported is set to 1 when the system linker allows */
/* response file, that is a file that contains the list of object files. */
/* This is useful on systems where the command line length is limited, */
/* meaning that putting all the object files on the command line can */
/* result in an unacceptable limit on the number of files. */
/* object_file_option denotes the system dependent linker option which */
/* allows object file names to be placed in a file and then passed to */
/* the linker. object_file_option must be set if objlist_file_supported */
/* is set to 1. */
/* link_max is a conservative system specific threshold (in bytes) of the */
/* argument length passed to the linker which will trigger a file being */
/* used instead of the command line directly. If the argument length is */
/* greater than this threshold, then an objlist_file will be generated */
/* and object_file_option and objlist_file_supported must be set. If */
/* objlist_file_supported is set to 0 (unsupported), then link_max is */
/* set to 2**31-1 so that the limit will never be exceeded. */
/* run_path_option is the system dependent linker option which specifies */
/* the run time path to use when loading dynamic libraries. This should */
/* be set to the null string if the system does not support dynamic */
/* loading of libraries. */
/* shared_libgnat_default gives the system dependent link method that */
/* be used by default for linking libgnat (shared or static) */
/* using_gnu_linker is set to 1 when the GNU linker is used under this */

/* RESPONSE FILE & GNU LINKER */
/* -------------------------- */
/* objlist_file_supported and using_gnu_link used together tell gnatlink */
/* to generate a GNU style response file. Note that object_file_option */
/* must be set to "" in this case, since no option is required for a */
/* response file to be passed to GNU ld. With a GNU linker we use the */
/* linker script to implement the response file feature. Any file passed */
/* in the GNU ld command line with an unknown extension is supposed to be */
/* a linker script. Each linker script augment the current configuration. */
/* The format of such response file is as follow : */
/* INPUT (obj1.p obj2.o ...) */
