As discussed on IRC, this adds an L suffix to C++ feature macros, as
specified by the std. I'd forgotten that in preprocessor-land, expressions
are evaluated as longs anyway, but the user might be trying to printf these
constants, or similar, where the type suffix is significant.
Jakub, Thomas:
cpp_define (pfile, "_OPENACC=201306");
cpp_define (pfile, "_OPENMP=201511");
those two macros might need suffixing too, but I don't have a std handy.
"the _OPENMP macro name is defined to have the
decimal value yyyymm where yyyy and mm are the year and month designations
of the version of the OpenMP API that the implementation supports."
I think that doesn't imply L suffix, but can ask.
'decimal value' is a confused term. It's a number with value, type and
representation. If it said the token yyyymmm where ..., I'd understand.
