[svn-r454] Changes since 19980702

----------------------

./src/H5T.c
	Prints statistics for no-op conversions also.

	For now, hardware floating point conversions may or may not
	raise SIGFPE depending on the hardware, operating system,
	etc.  Software conversions never raise SIGFPE and use +Inf or
	-Inf for overflow.

./test/dtypes.c
	Catches SIGFPE and causes the test to be skipped.  Better test
	for NaN.

./config/irix5.3
	Removed the -U_POSIX_SOURCE because it was removed from the
	main makefiles.

./bin/trace
./src/H5S.c
	Fixed a typo that prevented tracing info from being added to
	new API functions.
