	Untabify

Mon Jul 27 22:52:24 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/vector_support.h (doTestVec): 
	Remove "register" when declaring variable i

	* host/acosgen.c, host/cosgen.c, host/fmodgen.c, host/modfgen.c,
   	  host/tangen.c, host/asingen.c, host/coshgen.c, host/frexpgen.c,
  	  host/powgen.c, host/tanhgen.c, host/atan2gen.c, host/expgen.c,
    	  host/ldexpgen.c, host/singen.c, host/atangen.c, host/fabsgen.c,
   	  host/log10gen.c, host/sinhgen.c, host/ceilgen.c, host/floorgen.c,
  	  host/loggen.c, host/sqrtgen.c:
	Remove "register" when declaring variable "int x"

Mon Jul 27 22:45:01 1998  Jonathan Larmour  <[e-mail]>

	* 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]>

	* src/mathincl/fdlibm.h: 
	Rename CYGONCE_LIBM_FDLIBM_H to CYGONCE_LIBM_MATHINCL_FDLIBM_H as per
	code review comments

Fri Jul 24 22:20:42 1998  Jonathan Larmour  <[e-mail]>

	default matherr

Mon Jul 20 18:07:31 1998  Jonathan Larmour  <[e-mail]>

	* src/misc/infconst.c: 
	Oops. Don't let cyg_libm_infinity be static!

Thu Jul 16 20:07:26 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
	Cyg_libm_ieee_double_shape_type from ieeefp.h

	That type (which is a union) is now reordered so that it can be
	initialised in terms of two int's
