# command-line programs.
#
# BUILD_EXEEXT
#
# The filename extension for executables on the build
# platform. "" for Unix and ".exe" for Windows.
#
# TARGET_CC
#
# The name of a command that runs on the build platform
# and converts C source files into *.o files for the
# target platform. In other words, the cross-compiler.
#
# TARGET_CFLAGS
#
# Switches that the target compiler needs to turn C source files
# into *.o files. Do not include TARGET_TCL_INC in this list.
# Makefiles might add additional switches such as "-I.".
#
# TCL_*
#
# Lots of values are read in from the tclConfig.sh script,
# if that script is available. This values are used for
# constructing and installing the TCL extension.
#
# TARGET_READLINE_LIBS
#
# This is the library directives passed to the target linker
# that cause the executable to link against the readline library.
# This might be a switch like "-lreadline" or pathnames of library
# file like "../../src/libreadline.a".
#
# TARGET_READLINE_INC
#
# This variables define the directory that contain header
# files for the readline library. If the compiler is able
# to find <readline.h> on its own, then this can be blank.
#
# TARGET_LINK
#
# The name of the linker that combines *.o files generated
# by TARGET_CC into executables for the target platform.
#
# TARGET_LIBS
#
# Additional libraries or other switch that the target linker needs
# to build an executable on the target. Do not include
# on this list any libraries in TARGET_TCL_LIBS and
# TARGET_READLINE_LIBS, etc.
#
# TARGET_EXEEXT
#
# The filename extension for executables on the
# target platform. "" for Unix and ".exe" for windows.
#
# The generated configure script will make an attempt to guess
# at all of the above parameters. You can override any of
