No, clang gets invoked with the same flags, and fails the same way.

Yes. Plus removing '-C' from AM_CFLAGS reveals that there are other
flags that clang doesnʼt like.

The good news is that this affects only building from git, the
pre-release tarball builds fine with just './configure', and passes
all but one test from 'make check'.
