[svn-r9807] Purpose: bug fix
Description: For FreeBSD (sleipnir), when GNU compilers do conversion from unsigned long long to long double, the last 2 bytes of mantissa are lost. The impact of precision loss isn't significant. Solution: Detect this case on FreeBSD in configure, ignore it in dtypes.c test instead of return failure. Platforms tested: sleipnir, fuss, modi4. These systems are mainly concerned.
