/* At high optimization levels (e.g. gcc -O3), this function may be
* inlined in run_test_snprintf. This can trigger a spurious warning about
* potential misuse of snprintf from gcc -Wformat-truncation (observed with
* gcc 7.2). This warning makes tests in run_test_snprintf redundant on gcc
* only. They are still valid for other compilers. Avoid this warning by
* forbidding inlining of this function by gcc. */
