You're right in that limits.h for the AVR does not use #include_next. The
limits.h that the AVR toolchain uses is installed by gcc.
Unfortunately your suggestion makes the situation worse. There are now 4
failures instead of one:
FAIL: gcc.dg/pr36901-1.c (test for excess errors)
FAIL: gcc.dg/pr36901-4.c overflow (test for warnings, line )
FAIL: gcc.dg/pr36901-4.c overflow (test for errors, line )
FAIL: gcc.dg/pr36901-4.c (test for excess errors)
Here are the details from the log:
