[New-bugs-announce] [issue5781] Legacy float repr is used unnecessarily on some platforms

[Mark Dickinson]

New submission from Mark Dickinson <dickinsm at gmail.com>:

The current defines in pyport.h mean that we don't use Gay's code
for short float repr if there's evidence of double rounding.

However, there's one situation where double rounding occurs and we can 
still use Gay's code: namely, when the configure script has worked out how 
to get and set the x87 control word.

The pyport.h code should be fixed so that we use Gay's code in that 
situation.
