There is an application which requires 53 bit precision on some specific
double operation (for example, pkgsrc/lang/gauche; if interested, see
the comment in Scm_GetDouble() in src/number.c).

Does double (not long double) operation on i386-port still done in 53
bit precision after your change?

Otherwise, what is the preferred way to keep the behavior?
