# Arguments:

# Defines the following vars:
#
# DL_OBJS - Name of the object file that implements dynamic
# loading for Tcl on this system.
# DL_LIBS - Library file(s) to include in tclsh and other base
# applications in order for the "load" command to work.
# LDFLAGS - Flags to pass to the compiler when linking object
# files into an executable application binary such
# as tclsh.
# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
# that tell the run-time dynamic linker where to look
# for shared libraries such as libtcl.so. Depends on
# the variable LIB_RUNTIME_DIR in the Makefile.
# SHLIB_CFLAGS - Flags to pass to cc when compiling the components
# of a shared library (may request position-independent
# code, among other things).
# SHLIB_LD - Base command to use for combining object files
# into a shared library.
# SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
# creating shared libraries. This symbol typically
# goes at the end of the "ld" commands that build
# shared libraries. The value of the symbol is
# "${LIBS}" if all of the dependent libraries should
# be specified when creating a shared library. If
# dependent libraries should not be specified (as on
# SunOS 4.x, where they cause the link to fail, or in
# general if Tcl and Tk aren't themselves shared
# libraries), then this symbol has an empty string
# as its value.
# SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
# extensions. An empty string means we don't know how
# to use shared libraries on this platform.
# TCL_LIB_FILE - Name of the file that contains the Tcl library, such
# as libtcl7.8.so or libtcl7.8.a.
# TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
# in the shared library name, using the
# ${PACKAGE_VERSION} variable to put the version in
# the right place. This is used by platforms that
# need non-standard library names.
# Examples: ${PACKAGE_VERSION}.so.1.1 on NetBSD,
# since it needs to have a version after the .so, and
# ${PACKAGE_VERSION}.a on AIX, since the Tcl shared
# library needs to have a .a extension whereas shared
# objects for loadable extensions have a .so
# extension. Defaults to
# ${PACKAGE_VERSION}${SHLIB_SUFFIX}.
# TCL_NEEDS_EXP_FILE -
# 1 means that an export file is needed to link to a
# shared library.
# TCL_EXP_FILE - The name of the installed export / import file which
# should be used to link to the Tcl shared library.
# Empty if Tcl is unshared.
# TCL_BUILD_EXP_FILE -
# The name of the built export / import file which
# should be used to link to the Tcl shared library.
# Empty if Tcl is unshared.
# CFLAGS_DEBUG -
# Flags used when running the compiler in debug mode
# CFLAGS_OPTIMIZE -
# Flags used when running the compiler in optimize mode
# CFLAGS - We add CFLAGS to pass to the compiler

# - the N_TXTOFF on the `struct exec' must compute the seek address
