	Fixed the bug that if --without-sqlite3 is given, pkg-config is
	not properly used in configure script and failed to detect gnutls.
	This is because explicit call of PKG_PROG_PKG_CONFIG is missing
	and the initialization of pkg-config is done in first occurrence
	of PKG_CHECK_MODULES which is not executed because it is inside of
	sqlite3.m4. Added explicit PKG_PROG_PKG_CONFIG call.
	* configure.ac

 You have another version of autoconf.  It may work, but is not guaranteed to.
 If you have problems, you may need to regenerate the build system entirely.
 To do so, use the procedure documented by the package, typically `autoreconf'.])])
