* m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS) [dumpbin]: Adjust
lt_cv_sys_global_symbol_to_cdecl so that it declares imported
data symbols as __declspec(dllimport). Adjust
lt_cv_sys_global_symbol_to_c_name_address and
lt_cv_sys_global_symbol_to_c_name_address_lib_prefix so that they
fill in "(void*) 0" for imported data symbols. Add new
lt_cv_sys_global_symbol_to_import which finds imported data
symbols if non-empty and export this variable to the libtool script
in the global_symbol_to_import variable. Adjust
lt_cv_sys_global_symbol_pipe so that data imports can be located.
* build-aux/ltmain.in (func_generate_dlsyms): When data imports
are present, as indicated by global_symbol_to_import, generate
a relocation function lt_syminit that fills in the addresses
of data imports at runtime and point to the new function with a
new virtual @INIT@ entry in the symbol list.
* libltdl/loaders/preopen.c (add_symlist): Look for the virtual
@INIT@ symbol (i.e. lt_syminit) and call it.
(vm_sym): Step past the @INIT@ symbol, if present.
* tests/demo.at (dlmain.c): Call the @INIT@ symbol, if present.
