	* tests/vectors/vector_support.h (checkErrorAcceptable): 
	Add extra check for tolerance acceptance so it behaves correctly with
	underflow and overflow

	Also reverse sense of checkErrorAcceptable() so it now returns
	false on success and true on failure, as suggested by hmt. Change
	this in doTestVec() (which is where it is called) too.

	* tests/vectors/vector_support.h: 
	Remove #if 0'd shift_double() function

Mon Jul 27 21:55:04 1998  Jonathan Larmour  <[e-mail]>

	* include/math.h, include/sys/ieeefp.h, src/misc/infconst.c:
	Remove union Cyg_libm_int_double from math.h, which was used to
	define infinity, and replace with use of
