	*configure.ac (AM_PATH_GPG_ERROR): Require 0.3.

2003-08-19  Marcus Brinkmann  <[email protected]>

	The ath files (ath.h, ath.c, ath-pth.c, ath-pthread.c,
	ath-compat.c, ath-pth-compat.c and ath-pthread-compat.c) have been
	updated to have better thread support, and the Makefile.am was
	changed to reflect that.

	* util.h [!HAVE_FOPENCOOKIE]: Remove fopencookie declaration.
	* engine-gpgsm.c (gpgsm_assuan_simple_command): Set ERR to return
	value of status_fnc.
	* rungpg.c (start): Return SAVED_ERRNO, not errno.
