object files that are not referenced from @code{main} and uses export
lists.
@findex MODIFY_JNI_METHOD_CALL
@item MODIFY_JNI_METHOD_CALL (@var{mdecl})
Define this macro to a C expression representing a variant of the
method call @var{mdecl}, if Java Native Interface (JNI) methods
must be invoked differently from other methods on your target.
For example, on 32-bit Windows, JNI methods must be invoked using
the @code{stdcall} calling convention and this macro is then
defined as this expression:
@smallexample
build_type_attribute_variant (@var{mdecl},
build_tree_list
(get_identifier ("stdcall"),
NULL))
@end smallexample
@end table
