2012-03-21 H.J. Lu <hongjiu.lu@intel.com>
* stdio-common/_itoa.c: Check _ITOA_NEEDED instead of
LLONG_MAX != LONG_MAX.
(_itoa_word): Use _ITOA_WORD_TYPE on value.
(_fitoa_word): Likewise.
* stdio-common/_itowa.c: Check _ITOA_NEEDED instead of
LLONG_MAX != LONG_MAX.
* stdio-common/_itowa.h: Include <_itoa.h>.
(_itowa_word): Use _ITOA_WORD_TYPE on value.
(_itowa): New macro. Defined only if _ITOA_NEEDED is false.
* sysdeps/generic/_itoa.h (_ITOA_NEEDED): New macro. Defined
only if not defined.
(_ITOA_WORD_TYPE): Likewise.
(_itoa_word): Use _ITOA_WORD_TYPE on value.
Check !_ITOA_NEEDED instead of LONG_MAX == LLONG_MAX.

* sysdeps/sparc/fpu/libm-test-ulps: Update.
