[mingw|cygwin] Modify cwrapper to invoke target directly.
* libltdl/config/ltmain.m4sh (func_to_native_path):
new function. If $host is mingw, and $build is mingw
or cygwin, convert path to mingw native format.
(func_to_native_pathlist): new function. Ditto, for
:-separated pathlists.
(func_emit_cwrapperexe_src) [__CYGWIN__ && __STRICT_ANSI__]:
ensure putenv and setenv are declared. Define HAVE_SETENV.
(func_emit_cwrapperexe_src) [main]: add new constants to
hold desired PATH settings; initialize and convert to native
mingw format using functions above. Add new command-line
options --lt-env-set, --lt-env-prepend, and --lt-env-append.
No longer emit wrapper script as integral part of launching
child. Remove support for (now) unnecessary $TARGETSHELL.
Exec actual target executable directly.
(func_emit_cwrapperexe_src) [lt_setenv]: new function.
(func_emit_cwrapperexe_src) [lt_extend_str]: new function.
(func_emit_cwrapperexe_src) [lt_split_name_value]: new function.
(func_emit_cwrapperexe_src) [lt_opt_process_env_set]: new function.
(func_emit_cwrapperexe_src) [lt_opt_process_env_prepend]: new function.
(func_emit_cwrapperexe_src) [lt_opt_process_env_append]: new function.
(func_emit_cwrapperexe_src) [lt_update_exe_path]: new function.
(func_emit_cwrapperexe_src) [lt_update_lib_path]: new function.
