Raymond Lu 4dfad81062 [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.

/*-------------------------------------------------------------------------
* Function: test_particular_fp_integer
*
* Purpose: Tests hard conversions from floating numbers to integers in
* a special situation when the source is "float" and assigned
* the value of "INT_MAX". A compiler may do roundup making
* this value "INT_MAX+1". When this float value is casted to
* int, overflow happens. This test makes sure the library
* returns exception in this situation.
*
* Also verifies the library handles conversion from double to
* signed char correctly when the value of double is SCHAR_MAX.
* The test makes sure the signed char doesn't overflow.
*
* This test is mainly for netCDF's request.
*
* Return: Success: 0
*
* Failure: number of errors
