2005-10-27 Werner Koch <wk@g10code.com>
* gpg.c [__CYGWIN__]: Set default driver to winscard.dll.
* apdu.c, apdu.h: Updated from gnupg 1.9. Changes are:
* apdu.c [__CYGWIN__]: Make cygwin environment similar to _WIN32.
Suggested by John P. Clizbe.
* apdu.h (SW_HOST_NO_KEYPAD): New.
* apdu.c (host_sw_string): Support new code.
(reader_table_s): New field CHECK_KEYPAD.
(new_reader_slot, open_ct_reader, open_pcsc_reader)
(open_ccid_reader, open_rapdu_reader): Initialize it.
(check_ccid_keypad): New.
(apdu_check_keypad): New.
(apdu_send_le): Factored all code out to ...
(send_le): .. new. Takes an additional arg; changed all callers
of the orginal function to use this one with a NULL for the new
arg.
(apdu_send_simple_kp): New.
(ct_send_apdu, pcsc_send_apdu, my_rapdu_send_apdu)
(send_apdu_ccid): New arg PININFO.
(send_apdu_ccid): Use the new arg.
2005-10-26 David Shaw <dshaw@jabberwocky.com>
* keygen.c (proc_parameter_file): Default key and subkey usage
