Subject: [PATCH] Fix build on BSD systems
-
I tested FreeBSD, DragonflyBSD, NetBSD and OpenBSD and the endian
-
macros weren't necessary (and in fact caused errors) on all of them.
-
Because OpenBSD ships with an ancient GCC that doesn't support the
-
checked addition/multiplication builtins, the build there would fail
-
unless built with CC=cc or CC=clang. I changed configure.ac to prefer
-
cc over gcc, so that the distribution's compiler preference is
-
respected. (The default is [gcc cc]). I had to move AC_PROG_CC above
-
LT_INIT because otherwise LT_INIT would run AC_PROG_CC first, and we
-
wouldn't have a chance to use non-default parameters.
