I think there is *nothing* to lose having this functionnality 
optionnal. What about a -frecord-delim=(8byte|extensible) option, which 
would default to 8byte (as we currently do) and allow us, in the 
future, to have more possible choice about all this?

And I'd much like to see the simplistic "this is not standard, please 
wander away" argument not used any more here. There are many areas 
where the standard has less restrictions than reasonnably needed (and 
usually enforced by all compilers). We strive to provide a compiler of 
good quality, which includes providing a number of features not 
required by the standard.
