Kerberos V5 for movemail, including detection of V4 and V5 header
files and libraries.
Include <string.h> when STDC_HEADERS is defined, to get
declarations of string functions.
[KERBEROS5] (socket_connection): Support the current MIT Kerberos
V5 API rather than the old one.
[KERBEROS] (socket_connection): Change a constant name from
SOCKET_ERROR to POP_SOCKET_ERROR to avoid a namespace conflict
with a constant in a header file.
Macro SOCKET_ERROR undefined.
Don't declare h_errno.
[!WINDOWSNT]: Define macros recv and send.
[!WINDOWSNT] (POP_SERVICE): Change to pop3.
(pop_open) [WINDOWSNT]: Initialize trash_started.
(have_winsock) [WINDOWSNT]: New variable.
(socket_connection) [WINDOWSNT]: Initialize winsock.
(socket_connection): Use closesocket instead of close.
(getline): Use recv instead of read.
(fullwrite): Use send instead of write.
(pop_trash): Use closesocket instead of close.
(pop_trash) [WINDOWSNT]: Cleanup winsock.
Check if being called recursively by sendline.
fails, store the fact that we've searched it and don't search it
again after reading more data.
(getline): When determining whether or not it's necessary
to grow the input buffer, take into account the null that's stored
at the end of already-read input in the buffer.
defined, and if HAVE_CONFIG_H isn't defined, define
MAIL_USE_POP always (so that this file can be included in
other programs besides emacs).
Only declare h_errno if HAVE_H_ERRNO isn't defined or
HAVE_CONFIG_H isn't defined.
(find_crlf, getline): Instead of using strstr, use a
custom function for finding CRLF.
(my_strstr): Function deleted.
Don't include string.h or strings.h.
Include des.h before krb.h.
Do declare my_strstr.
(getline): Really use my_strstr.
Leave one empty place in server->buffer,
and put a null at the end of the data in it.
