Synopsis: __dtoa broken with -O2 or -O3 optimisation

State-Changed-From-To: open->closed
State-Changed-By: das
State-Changed-When: Mon Mar 31 04:11:31 PST 2003
State-Changed-Why: 
This problem is due to the fact that gcc3 with -fstrict-aliasing
does not produce the intended output for code that violates C's
aliasing rules.  Seems to happen only for quantities > 32-bits.

The new version of dtoa() imported a few weeks ago does not violate
C's aliasing rules and seems to work properly.  I do not intend to
MFC this code, but then again, the old code works fine with gcc2.
