Indeed. It makes parsing a little more awkward as (short) 1 is not a postfix expression. I suppose adding additional suffixes for char/short conditional on -fgimple would be another way (either via setting user_literals option or teaching libcpp about those itself). 's' and 'ss' (CPP_N_SMALL_SMALL and CPP_N_SMALL_SMALL_SMALL?) would be my choice... I'll give the (short) 1 parsing a try though to see how awkward it really gets. Thanks, Richard.
