// GCC header limits.h recursively includes itself through another header called
// syslimits.h for some reason. This setup breaks down if we directly
// #include_next GCC's limits.h (reasons not entirely clear to me).
// See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107795 for more details.
// Therefore, we manually re-create the necessary include sequence below:

// Get the system limits.h defines (force recurse into the next level)
#define _GCC_LIMITS_H_
#define _GCC_NEXT_LIMITS_H
#include_next <limits.h>

// Get the ISO C defines
#undef _GCC_LIMITS_H_
#include_next <limits.h>

#else

#  if __has_include_next(<limits.h>)
#    include_next <limits.h>
