  Support for MSVC compiler: Avoid division by a literal 0.
  
  * lib/math.in.h (NAN): Define through a function call also on MSVC.
  * m4/frexp.m4 (gl_FUNC_FREXP_WORKS): Divide by 'zero' instead of 0.0.
  * m4/printf.m4 (gl_PRINTF_INFINITE, gl_PRINTF_DIRECTIVE_A,
  gl_PRINTF_DIRECTIVE_F, gl_PRINTF_FLAG_ZERO): Likewise.
  (gl_PRINTF_INFINITE_LONG_DOUBLE): Divide by 'zeroL' instead of 0.0L.
  * tests/infinity.h: New file.
  * tests/nan.h (NaNf, NaNd, NaNl): Define through a function call also
  on MSVC.
