1035#                       for shared libraries such as libtcl.so.  Depends on
1036#                       the variable LIB_RUNTIME_DIR in the Makefile.
1037#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
1038#                       of a shared library (may request position-independent
1039#                       code, among other things).
1040#       SHLIB_LD -      Base command to use for combining object files
1041#                       into a shared library.
1042#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
1043#                       creating shared libraries.  This symbol typically
1044#                       goes at the end of the "ld" commands that build
1045#                       shared libraries. The value of the symbol defaults to
1046#                       "${LIBS}" if all of the dependent libraries should
1047#                       be specified when creating a shared library.  If
1048#                       dependent libraries should not be specified (as on
1049#                       SunOS 4.x, where they cause the link to fail, or in
1050#                       general if Tcl and Tk aren't themselves shared
1051#                       libraries), then this symbol has an empty string
1052#                       as its value.
1053#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
1054#                       extensions.  An empty string means we don't know how
1055#                       to use shared libraries on this platform.
1056#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
1057#                       in a static or shared library name, using the $PACKAGE_VERSION variable
1058#                       to put the version in the right place.  This is used
1059#                       by platforms that need non-standard library names.
1060#                       Examples:  ${PACKAGE_VERSION}.so.1.1 on NetBSD, since it needs
1061#                       to have a version after the .so, and ${PACKAGE_VERSION}.a
1062#                       on AIX, since a shared library needs to have
1063#                       a .a extension whereas shared objects for loadable
1064#                       extensions have a .so extension.  Defaults to
1065#                       ${PACKAGE_VERSION}${SHLIB_SUFFIX}.
