alloc-pool.c: Don't check HAVE_LONG_DOUBLE.

gcc:
	* alloc-pool.c: Don't check HAVE_LONG_DOUBLE.
	* fixinc/gnu-regex.c: Don't define `volatile'.
	* ggc-page.c: Don't check HAVE_LONG_DOUBLE.
	* ggc-simple.c: Likewise.
	* system.h: Don't define `volatile'.

	* aclocal.m4 (gcc_AC_C_VOLATILE, gcc_AC_C_LONG_DOUBLE): Delete.
	* configure.in (gcc_AC_C_VOLATILE, gcc_AC_C_LONG_DOUBLE): Don't
	call these macros.
	* config.in, configure: Regenerated.

include:
	* ansidecl.h: Delete HAVE_LONG_DOUBLE GCC bootstrap support.
