[svn-r5452]

Purpose:
eliminating the compiler warnings in Windows


Solution:
I am eliminating the compiler warnings in Windows.
the last 2 were:

1)
if((oid_list = H5MM_malloc(oid_count*sizeof(hid_t)))==NULL)
HGOTO_ERROR(H5E_RESOURCE, H5E_NOSPACE, NULL,
"memory allocation failed");

D:\disk_w\hdf5\src\H5F.c(2590) : warning C4047: '=' : 'int ' differs in levels
of indirection from 'void *'

on the HGOTO_ERROR call , I replaced the NULL with FAIL

2)
*((float*)d) = *((double*)s);
D:\disk_w\hdf5\src\H5Tconv.c(6426) : warning C4244: '=' : conversion from 'double ' to 'float ', possible loss of data

I added the type cast
*((float*)d) = (float) *((double*)s);

we have now 0 errors 0 warnings on Windows !








Platforms tested:
