Gnulib portability library has 
https://www.gnu.org/software/gnulib/manual/html_node/Integer-Range-Overflow.html and https://www.gnu.org/softwarhe/gnulib/manual/html_node/Integer-Type-Overflow.html and even macros for producing well-defined integer wraparound for signed integers: https://www.gnu.org/software/gnulib/manual/html_node/Wraparound-Arithmetic.html

That code is under GPL but I believe there is no problem if someone just looks into that for ideas on how to write similar macros.
