Good morning/afternoon/evening, all.
I've been writing some position independent data structure code.
As such, I've been using ptrdiff_t.
I've just noticed, while compiling, that my GCC (6.3.0) has ptrdiff_t
as a volatile long int.
I doubt gcc does that. More likely your code has a broken macro
somewhere. You don't provide enough information for us to help more...
I thought I'd given enough for the question :-)
But I think you might be right indeed.
I've just had another line of output from GCC when it's unhappy with my
code, which is this;
"note: expected ‘lfds720_pal_uint_t * {aka long long unsigned int *}’
but argument is of type ‘ptrdiff_t * {aka long int *}’"
Now before I was being told a ptrdiff_t was a volatile long int.
It looks like if I add volatile to a type, it turns up in the "aka".
I was not expecting this - I thought the aka would be the underlying
type, sans qualifiers.
