#--------------------------------------------------------------------
# The statements below define a collection of symbols related to
# dynamic loading and shared libraries:
#
# 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.
# LD_FLAGS - 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.
# MAKE_LIB - Command to execute to build the Tcl library;
# differs depending on whether or not Tcl is being
# compiled as a shared library.
# 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 $VERSION variable
# to put the version in the right place. This is used
# by platforms that need non-standard library names.
# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
# to have a version after the .so, and ${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
# ${VERSION}${SHLIB_SUFFIX}.
#--------------------------------------------------------------------
# Step 1: set the variable "system" to hold the name and version number
# for the system. This can usually be done via the "uname" command, but
# there are a few systems, like Next, where this doesn't work.

# Loading for Tcl -- What Became of It?". Proc. 2nd Tcl/Tk Workshop,
# New Orleans, LA, Computerized Processes Unlimited, 1994), then we need

# support only a file format that is more or less version-7-compatible.
# In particular,
# - a.out files must begin with `struct exec'.
# - the N_TXTOFF on the `struct exec' must compute the seek address
# of the text segment
# - The `struct exec' must contain a_magic, a_text, a_data, a_bss
# and a_entry fields.
# The following compilation should succeed if and only if either sys/exec.h
# or a.out.h is usable for the purpose.
#
# Note that the modified COFF format used on MIPS Ultrix 4.x is usable; the
