[Cfp-interest 1236] Action Item: Evaluation of Literals

[Ian McIntosh]

Last meeting I was wrong.  C++ does not have a pragma to control 
literal evaluation precision.  It just does it the right way.

Some approaches we could take:

1.  Do nothing.
2.  Treat this as a bug in the current standard and change it to 
match C++ (likely getting complaints).
3.  Make it an implementation option, so the compiler vendor has to 
document what they do.
4.  Add a compiler-defined macro so the program can detect what the 
compiler will do, and possibly select alternate code like explicitly 
converting precision.
5.  Add a user-defined macro so the program can tell the compiler 
what to do (eg, new improved behavior or stay compatible with old).
6.  Same as #5 but with a pragma.
7.  Other?
