annotate utils.h @ 203:3a25180d3a5c
Abort on line numbering or column numbering overflow.
Line numbers are limited to values that fit in "unsigned int". Also
reject input lines longer than 2^32-1 characters. It seems reasonable
to presume that any input that violates these constraints is someone
screwing around and not a serious attempt to compile or preprocess
anything useful. Done in response to n2129, but without getting into
any of the silliness found there.
