See individual patches for details.

Pino Toscano (5):
  Include signal.h
  Remove unused variables
  Push -Wsuggest-attribute=noreturn only with GCC
  tests: do not set libguestfs environment variables
  Define the GCC version macro

Isolate the GCC pragmas properly; since clang defines __GNUC__,
explicitly check for __clang__ too.

Carry over the GUESTFS_GCC_VERSION macros from libguestfs, that defines
the GCC version as single number; also, rename it to P2V_GCC_VERSION,
and limit it to GCC (defined to 0 for any other compiler).

I guess we test against the installed virt-v2v?  That's fine.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
http://libguestfs.org/virt-v2v

This is all fine, ACK series.

Thanks,

Rich.
