* uinfo.cc (pwdgrp::fetch_account_from_windows): Fix gid evaluation
	for local accounts.
	* libc/sys/rtems/sys/cpuset.h (CPU_SET_S): Add const qualifier.
	(CPU_SET): Likewise.
	* cygserver-config: Use numeric id 18 instead of "system" in chown.
	* net.cc (cygwin_setsockopt): Ignore IPV6_TCLASS the same way as IP_TOS.
*** empty log message ***
	* pwdgrp.cc (client_request_pwdgrp::pwd_serve): Add 1 to the message
	length to account for the trailing NUL.
	* cygtls.h (TP_NUM_C_BUFS): Raise to 50 to allow SYMLOOP_MAX recursions
	path_conv <-> normalize_posix_path, plus a bit of buffer.
	(TP_NUM_W_BUFS): Ditto.
	(class san): Change type of _c_cnt and _w_cnt to unsigned.
	* path.cc (normalize_posix_path): Guard recursion into path_conv
	against tmp_pathbuf overflow.  Generate normalized path in call to
	path_conv.  If the path is valid, replace dst with the normalized_path
	from path_conv call.  Add comment to explain why we're doing this.
	* tls_pbuf.cc (tls_pathbuf::destroy): Only free buffers until the
	first buffer pointer is NULL.
	(tmp_pathbuf::c_get): Simplify error message.
	(tmp_pathbuf::w_get): Ditto.
	* tls_pbuf.h (class tmp_pathbuf): Change type of c_buf_old and w_buf_old
	to unsigned.
	(tmp_pathbuf::check_usage): New inline method to check if we have
	enough tmp_pathbuf buffers left to call a function using tmp_pathbuf
	buffers.
	* tlsoffsets.h: Regenerate.
	* tlsoffsets64.h: Regenerate.
	* winf.cc (linebuf::fromargv): Temporarily revert patch from 2014-01-24.
