The MSVC 9 compiler gives a compilation error for a division through a
literal whose value is zero. We can work around it like we did for NaN
that also triggered bugs in various compilers.
2011-09-11 Bruno Haible <address@hidden>
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.
* tests/test-ceilf1.c: Include infinity.h.
