We are going to use static_assert provided by <assert.h> or, if it doesn't work, our cheap imitation that doesn't display the message specified as the second argument of static_assert. * configure.ac (AC_CACHE_CHECK): Check for static_assert in <assert.h>, define HAVE_STATIC_ASSERT if it is available. * static_assert.h: New file. * Makefile.am (strace_SOURCES): Add it.
