How to disable double and long double?

[Petar Penchev]

Hello All,
Is it possible to disbable support for floating point operations with  
double precision types and operations i.e. I wont to remove
'double' and 'long double' support in gcc.

I tried to define float and double size to be the same , but it did not  
work.
Is there a configure parameter which does that or there is another way ?

Regards
