* gjavah.c (main): Handle --output-class-directory argument. * jvspec.c (lang_specific_driver): Translate `-d' into -foutput-class-dir. * jcf.h (jcf_write_base_directory): Declare. * lang.c (lang_decode_option): Recognize -foutput-class-dir. * lang-options.h: Mention -foutput-class-dir. * jcf-write.c (jcf_write_base_directory): New global. (make_class_file_name): Put generated .class file into `-d' directory, or into source directory if -d not given. Function now static. (write_classfile): Free class file name. Handle case where class file name is NULL. (DIR_SEPARATOR): New macro. Include <sys/stat.h> From-SVN: r23640
