Building on OpenBSD about macemu HOT 3 OPEN

I'm running into the same issue with FreeBSD 10.1-RELEASE amd64 - the issue seems to be that the generated Makefiles are incorrect.

The line it seizes on, when handling the obj/sigsegv.o, should simply be re-executed manually with -DHAVE_SIGINFO_T after which make may proceed as normal.

Of course, what really needs to happen is that people need to stop only caring about Linux as a release platform (or OS X/Windows), and make goddamn portable build systems, like, say, autoconf and friends are explicitly designed to do...

You're not being monumentally dense, don't worry.

Sounds like the autoconf detection needs to be fixed to correctly detect HAVE_SIGINFO_T on FreeBSD. I guess no one has looked at this part yet?

from macemu.

It looks like configure.ac tries to compile the following program to check if HAVE_SIGINFO_T works:

  #ifdef HAVE_UNISTD_H
  #include <unistd.h>
  #endif
  #define HAVE_SIGINFO_T 1
  #define CONFIGURE_TEST_SIGSEGV_RECOVERY
  #include "../CrossPlatform/vm_alloc.cpp"
  #include "../CrossPlatform/sigsegv.cpp"

Can you check if that doesn't compile on FreeBSD and if so, why? It might be something simple we can just fix by e.g. including another header needed by that program.
