If I remember correctly, we are supposed to parse compiler-specific extensions
before UDLs - i.e. The compiler extensions get dibs.
I guess that's not the issue. You propose being able to turn off (presumably
all?) gcc-specific suffix extensions. Presumably, these should be on by
default for C++1*? I agree we should have something like this.
Detecting at the level of c-family or the lexer whether c++ has seen a
definition of operator"" r or i could be ... real interesting.
Perhaps we could "move" these gnu extensions to:
namespace __gnucxx{
operator"" r()
}
somehow.
