#	2. SGI systems don't use the BSD form of the gettimeofday function,

#	3. See if gettimeofday is declared in the <sys/time.h> header file.
#	   if not, set the GETTOD_NOT_DECLARED flag so that tclPort.h can

#	Check for the existence of the -lsocket and -lnsl libraries.
#	The order here is important, so that they end up in the right
#	order in the command line generated by make.  Here are some
#	special considerations:
#	1. Use "connect" and "accept" to check for -lsocket, and
#	   "gethostbyname" to check for -lnsl.
#	2. Use each function name only once:  can't redo a check because
#	   autoconf caches the results of the last check and won't redo it.
#	3. Use -lnsl and -lsocket only if they supply procedures that
#	   aren't already present in the normal libraries.  This is because
#	   IRIX 5.2 has libraries, but they aren't needed and they're
#	   bogus:  they goof up name resolution if used.
#	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
#	   To get around this problem, check for both libraries together
#	   if -lsocket doesn't work by itself.

#--------------------------------------------------------------------
#	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.

# Step 4: If pseudo-static linking is in use (see K. B. Kenny, "Dynamic
# Loading for Tcl -- What Became of It?".  Proc. 2nd Tcl/Tk Workshop,
# New Orleans, LA, Computerized Processes Unlimited, 1994), then we need
# to determine which of several header files defines the a.out file
# format (a.out.h, sys/exec.h, or sys/exec_aout.h).  At present, we
# 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
# `struct exec' includes a second header that contains information that
# duplicates the v7 fields that are needed.
