2005-05-19  Joachim Klein  <joachim@ltl2dstar.de>

	* DRA2NBA.hpp, SafrasAlgorithm.cpp: rename variables _I, _J, _N
	because they may clash with C macro definitions (_N on Solaris)

	* common/RunProgram.posix.cpp: rename stdin, stdout, stderr to
	std_in, std_out, std_out to avoid confusion with predefined std*
	with some compilers/system header files.

	* ltl2dstar_main.cpp: fix argc handling of command line options
