Patch 7.4.1440 (after 7.4.1437)
Problem: Can't build on Windows.
Solution: Change #ifdefs. Only define isnan when used.
Files: src/macros.h, src/eval.c, src/json.c
I get this build failure on HP-UX after this patch:

It has to do with FEAT_FLOAT and isnan() and isinf() being defined as
macros if _INCLUDE_HPUX_SOURCE is defined in HP-UX's math.h:
<snip>
...
# define isnan(x) _ISNAN(x)
# define isinf(x) _ISINF(x)
...
# define _IS64(x) (sizeof(x)==sizeof(double))
# define _IS32(x) (sizeof(x)==sizeof(float))
...
# define _ISNAN(x)
(_IS32(x)?_Isnanf(x):_IS64(x)?(isnan)(x):_Isnanf80(x))
# define _ISINF(x)
(_IS32(x)?_Isinff(x):_IS64(x)?_Isinf(x):_Isinff80(x))
...
</snip>
Defining HAVE_ISNAN and HAVE_ISINF in src/auto/config.h fixes the
problem which leads me to think that the configure test for these two
functions isn't right somehow.
I'm not sure how to fix it though.
