# Variables defined here:
#
# NAT_FILE - The header file with definitions for this native target.
#
# NATDEPFILES - Source files required for native debugging on this
#               native target.
#
# NAT_CDEPS - Dynamic symbols to be exported for libthread_db.
#
# LOADLIBES - Libraries against which GDB will be linked for this
#             native target.
#
# MH_CFLAGS - Additional CFLAGS for this host.
#
# XM_CLIBS - Host-dependent libraries against which GDB will be linked
#            for this native target.
#
# HAVE_NATIVE_GCORE_HOST - Whether gcore should be installed on this
#                          native target.
#
# nat_makefile_frag - Name of the (optional) Makefile fragment file
#                     required to build the native target.  The
#                     fragment is incorporated into the Makefile that
#                     configure constructs from Makefile.in.
#
# Notes:
#
# - To avoid shell expansion of variables, declare them with single
#   quotes.
#
# - nat_makefile_frag must contain the full path of the file.


# This first case is useful for filling default values for each
# gdb_host.
