aclocal.m4 (gcc_AC_C_CHARSET, [...]): New macros.

Browse source 
* aclocal.m4 (gcc_AC_C_CHARSET, gcc_AC_C_COMPILE_BIGENDIAN,
	gcc_AC_C_FLOAT_FORMAT): New macros.
	* configure.in: Add AC_PROG_CPP after CC tests;
	gcc_AC_C_CHARSET and gcc_AC_C_FLOAT_FORMAT after the sizeof
	tests; and gcc_AC_C_COMPILE_BIGENDIAN after gcc_AC_C_CHAR_BIT.
	* configure, config.in: Regenerate.

	* config/rs6000/aix.h: Define COLLECT_EXPORT_LIST here.

	* config.gcc: Remove references to deleted files.
	(i370-*-opened*): Use i370/xm-mvs.h (which now defines only
	FATAL_EXIT_CODE, which is the same between oe and mvs).
