sizeof(long double) is a property of the ABI not the OS.
Under Linux/Sparc we, unfortunately, did not follow the ABI, so
effectively we do have an OS-specific Sparc 32-bit ABI in that
we use 8 byte long doubles.
The value of long double can be set at run time by examining information
provided by the BFD. ARM does this for the ABI, MIPS this for almost
everything.
I don't see mips-tdep.c using bfd information in it's one and only
call to set_gdbarch_long_double_bit(), what am I overlooking?
