	(__quadmath_extern_inline): Define.
	(cimagq, conjq, crealq): New inlines.
	* Makefile.am (libquadmath_la_SOURCES): Add math/cimagq.c,
	math/conjq.c, math/cprojq.c, math/crealq.c, math/fdimq.c,
	math/fmaxq.c, math/fminq.c, math/ilogbq.c, math/llrintq.c,

	fminq, ilogbq, llrintq, log2q, lrintq, nearbyintq, remquoq): Add.
	* quadmath-imp.h (__LITTLE_ENDIAN__): Don't define.
	(ieee854_float128): Use __BYTE_ORDER == __ORDER_BIG_ENDIAN__
	tests instead of __BIG_ENDIAN__.
	* quadmath.map (QUADMATH_1.0): Add cimagq, conjq, cprojq, crealq,
	fdimq, fmaxq, fminq, ilogbq, llrintq, log2q, lrintq, nearbyintq
