But I'm still confused as to how this works for you. Any idea about that? :-)
Oh, I see it now. For me, -DLIBXL_API_VERSION=0x040400 landed in CFLAGS,
not only LIBXL_CFLAGS. According to config.log it happened just after
testing for xenlight - first, the test using pkg-config failed (something
wrong with my libxl installation), but then fallback to manual check.
And since then, every gcc call have -DLIBXL_API_VERSION=0x040400.
Looking at m4/virt-driver-libxl.m4, I think it's because saved
old_CFLAGS is overridden by LIBVIRT_CHECK_LIB with actual CFLAGS (now
containing -DLIBXL_API_VERSION=0x040400).
