What have you done in the way of command-line options to enable the new features? Specifically: * Decimal fp constants are already preprocessing numbers in the standard syntax - but in standard C their conversion to a token requires a diagnostic (at least a pedwarn with -pedantic). If decimal fp is to be usable with -pedantic an option is needed to disable that pedwarn/error. * There is also an arguable case for diagnosing any use of the new keywords if -pedantic, unless such a special option is passed. * Any choice of TTDT other than "double" (properly, the type specified by FLT_EVAL_METHOD, but we don't implement that) would also be incompatible with C99 and need specifically enabling. (Previous versions of the DTR - such as the one linked from svn.html - also provided defined behavior for out-of-range conversions between binary float and integer types. This appears to have been removed in the latest draft, so no code to implement this is needed. However, such code would also have needed to be conditional unless benchmarking as per bug 21360 showed no performance impact.) -- Joseph S.
