874 #                       code, among other things).

876 #                       into a shared library.
877 #       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
878 #                       creating shared libraries.  This symbol typically
879 #                       goes at the end of the "ld" commands that build

886 #                       libraries), then this symbol has an empty string

888 #       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
889 #                       extensions.  An empty string means we don't know how
890 #                       to use shared libraries on this platform.
891 #       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
892 #                       in a static or shared library name, using the $VERSION variable
893 #                       to put the version in the right place.  This is used
894 #                       by platforms that need non-standard library names.
895 #                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
896 #                       to have a version after the .so, and ${VERSION}.a
897 #                       on AIX, since a shared library needs to have
898 #                       a .a extension whereas shared objects for loadable
899 #                       extensions have a .so extension.  Defaults to
900 #                       ${VERSION}${SHLIB_SUFFIX}.
901 #       TCL_NEEDS_EXP_FILE -
902 #                       1 means that an export file is needed to link to a
903 #                       shared library.
904 #       TCL_EXP_FILE -  The name of the installed export / import file which
905 #                       should be used to link to the Tcl shared library.
906 #                       Empty if Tcl is unshared.
907 #       TCL_BUILD_EXP_FILE -

909 #                       should be used to link to the Tcl shared library.
910 #                       Empty if Tcl is unshared.
911 #       CFLAGS_DEBUG -
912 #                       Flags used when running the compiler in debug mode
913 #       CFLAGS_OPTIMIZE -
914 #                       Flags used when running the compiler in optimize mode
