--- Comment #9 from Jonny Grant <jg at jguk dot org> ---
I'm sure you all know more than me.
But I understood #line 0 was not allowed. Therefore, it can simply be
unsigned, and 0 used to indicate an error, instead of negative values.
#line 0 is not currently an error, but probably should right? file line numbers
start at 1.
If it was changed to a uint64, at least this issue wouldn't occur for a long
time.
BTW, could this message clarify what the supported range is? Probably
2147483648 ?
