Thanks for the information. I have not seen it before (I have just
checked the gcc info file now).
Do you know if this is recent because, STk is compiled with gcc for
years and I have not seen the problem so far. I know that I'm mainly
on i386, which has very few registers, and it can explain, but others
have not signalled this kind of problem. Weird....
