rgbds: FreeBSD: v0.6.0 clang build fails

Hello,

v0.6.0 doesn’t build with clang 14.0.5 and 13.0.0:

cc -O2 -pipe  -fstack-protector-strong -fno-strict-aliasing  -Wall -pedantic -std=gnu11 -I include  -D_POSIX_C_SOURCE=200809L -D_ISOC11_SOURCE -c -o src/asm/main.o src/asm/main.c

            if (!(isascii(*__low) && (__tab_[static_cast<int>(*__low)] & __m)))

14.0.5 log 13.0.0 log

But it build fine with clang 10.0.1: log

Any hints?

Thanks
