We have the same situation with GDAL. It requires C++11 [1]. Although this may not set the requirement absolutely, it sets it practically. Additionally, increasing the minimum for C let's say to C17, may allow increasing the minimum for C++ because practically there is no compiler which would support one and not the other, but that depends on the particular combination. In CI, I have set the GCC compilation tests only for C99 and above and C++11 and above [2] (i.e., not requiring anything below that). However, note that the C is GNU C, not ISO (which we currently don't conform to). The "pedantic" keeping of the standard fails for both C and C++ (and thus it is not currently checked in the CI).
