# OBJS List of object files to include in library
# SHLIB_LINK If shared library relies on other libraries,
# additional stuff to put in its link command
+# SHLIB_PREREQS Order-only prerequisites for library build target
# SHLIB_EXPORTS (optional) Name of file containing list of symbols to
# export, in the format "function_name number"
#
# SO_MINOR_VERSION Minor version number to use for shared library
# (If you want a patchlevel, include it in SO_MINOR_VERSION, e.g., "6.2".)
#
-# Optional flags when building DLL's (only applicable to win32 and cygwin
-# platforms).
-# DLLTOOL_DEFFLAGS Additional flags when creating the dll .def file
-# DLLTOOL_LIBFLAGS Additional flags when creating the lib<module>.a file
-# DLLWRAP_FLAGS Additional flags to dllwrap
-#
# The module Makefile must also include
# $(top_builddir)/src/Makefile.global before including this file.
# (Makefile.global sets PORTNAME and other needed symbols.)
-# Automatically append LDFLAGS and LDFLAGS_SL to SHLIB_LINK
