I do it also on Windows 7/win32.
I tried both 2.4.4 and 2.5.1 as the starting compiler.
this compiles: make clean all
this does not: make clean all OPT="-gwl"

Some algorithms convert faster with increased accuracy.

Yes, because it's strange programming model should be really dropped.
Agree, but the 80 bit support makes some people want to use it.
