How are we going to resolve it?
I don't think there's any conflict between the mangling DF<number>_ for _FloatN, and DF<number>[ijstlmxy]<number>[sn] for fixed point. If DF is followed by a number, the following character is '_' for _FloatN and the code for an integer type for fixed point. -- Joseph S. Myers jos...@codesourcery.com
