I've made this change for v2.  In my testing on Fedora 38, it didn't seem
that additonal_flags=-std=c11 was required for gcc, but I made this change
anyway.  (I'd guess that it might be necessary for some older version of
gcc.)  Also, I found that testing with CC_FOR_TARGET=clang didn't work
(but not due to adding -std=c11), so I fixed that problem too.

Thanks for this suggestion!
