* configure.ac: Remove all uses of GNUPG_CHECK_TYPEDEF, for byte,
	ushort, ulong, u16 and u32.
	* acinclude.m4 (GNUPG_CHECK_TYPEDEF): Remove macro.

2003-01-29  Marcus Brinkmann  <marcus@g10code.de>

	* types.h: Remove byte and ulong types.
	* util.h (_gpgme_hextobyte): Change prototype to unsigned char
	instead byte.
	* conversion.c (_gpgme_hextobyte): Change argument to unsigned
	char instead byte.
	(_gpgme_decode_c_string): Likewise, and beautify.  Also support a
	few more escaped characters.  Be more strict about buffer size.
	(_gpgme_data_append_percentstring_for_xml): Change type of SRC,
	BUF and DST to unsigned char instead byte.
	* progress.c (_gpgme_progress_status_handler): Use unsigned char
	instead byte.
	* debug.c (trim_spaces): Likewise.
