Appears that configure doesn't properly detect the case when clang is used instead of gcc:

CC=clang ./configure runs fine, but produces a long list of warning flags that clang doesn't support:

configure: Warning Flags: -W -Waddress -Wall -Warray-bounds -Wattributes -Wbad-function-cast ... trimmed ...

At some point, compilation fails:

CC libvirt_util_la-viralloc.lo clang: error: unknown warning option '-Wclobbered' [-Werror,-Wunknown-warning-option] clang: error: unknown warning option '-Wcoverage-mismatch'; did you mean '-Wpointer-type-mismatch'? [-Werror,-Wunknown-warning-option]

and many other similar errors.

Any idea what would be a proper fix for that?

clang annoyingly just ignores unknown warning flags by default causing our flag detection code to fail. I'm working on a fix for this.
