# This is the target specific configuration file.  This is invoked by the
2
# autoconf generated configure script.  Putting it in a separate shell file

# lets us skip running autoconf when modifying target specific information.

# This file switches on the shell variable ${target}, and sets the
6
# following shell variables:
7
#  config_path          An ordered list of directories to search for
8
#                       sources and headers.  This is relative to the
9
#                       config subdirectory of the source tree.

#  XCFLAGS              Add extra compile flags to use.
