This -# differes from the SHLIB_CFLAGS as it is not used -# when building object files or executables. -# 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.

But -# of course the Tcl version of this is only used for Tcl. -# LIB_SUFFIX - Specifies everything that comes after the "libfoo" -# in a static or 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 a shared library needs to have -# a .a extension whereas shared objects for loadable -# extensions have a .so extension.
