[svn-r12435] Purpose: Bug fix
Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned)
long long to long double. When the bit sequences are 0x003ff..., 0x007fff...,
0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big
as they should be.
Solution: Detect the error in configure and disable the compiler conversion
and test case.
Platforms tested: h5committest, Mac OS 10.4, and fuss.
