    #	  of the text segment

    #	  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.

#                       applications in order for the "load" command to work.
#       LDFLAGS -      Flags to pass to the compiler when linking object

#                       as tclsh.

#                       code, among other things).

#                       SunOS 4.x, where they cause the link to fail, or in

#                       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

#                       on AIX, since a shared library needs to have
#                       a .a extension whereas shared objects for loadable
#                       objects for loadable extensions have a .so
