of bugs exposed by this test in order for it to pass.
Currently the prefix is hardcoded as 'lib', as I am not aware

condition out of test loop to be sure that each originator is
tried, instead of erroring out if the first doesn't match.
Support passing NULL as the originator to load all preloaded

module names with no directory component before searching the
filesystem for a match.
* libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Declare
a new global_symbol_to_c_name_address_lib_prefix variable.

* libltdl/config/ltmain.m4sh (func_generate_dlsyms): In order

broken execv.
(func_mode_link) [cygwin|mingw]: Don't call dirname and
basename directly; use func_dirname and func_basename
when computing cwrapper names. Use cwrapper to generate
wrapper script, and use pathname returned by
func_ltwrapper_scriptname instead of $output.
(func_mode_link) [NOT cygwin|mingw]: move wrapper script
generation for non-win32 inside case statement, as default
case.
(func_mode_uninstall) [$name's extension != .lo|.la]:

wrapper script, or if it is a libtool wrapper executable.

(func_emit_libtool_cwrapperexe_source): replace DEBUG() macro

embed script text in C char* static variable.
(f_e_l_c_s: main): add new option --lt-dump-script, parse argv[]
for it, and take appropriate action. Call chase_symlinks()
on argv[0], in case this.exe was launched via one. Use chased
value to determine full absolute pathname of wrapper script, in
$objdir. Unconditionally write script out to this pathname and
set permission bits. Remove extraneous ';' from debugging loop.
(f_e_l_c_s: main) [mingw]: DOS-ize $SHELL before populating
newargv[0]; if $TARGETSHELL environment variable is set, use
it instead of $SHELL and do not DOS-ize. Ensure newargv[1]
(wrapper script absolute path) uses only '/', not '\'. Make
sure to call execv() with DOS-ized $SHELL (or un-DOS-ized
$TARGETSHELL, if set)
