++#
++#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
++#
++# DESCRIPTION
++#
++#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
++#   added in between.
++#
++#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
++#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
++#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
++#   FLAG.
++#
++#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

++# SYNOPSIS
++#
++#   AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
++#
++# DESCRIPTION
++#
++#   For every FLAG1, FLAG2 it is checked whether the linker works with the
++#   flag.  If it does, the flag is added FLAGS-VARIABLE
++#
++#   If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
++#   used. During the check the flag is always added to the linker's flags.
++#
++#   If EXTRA-FLAGS is defined, it is added to the linker's default flags
++#   when the check is done.  The check is thus made with the flags: "LDFLAGS
++#   EXTRA-FLAGS FLAG".  This can for example be used to force the linker to
++#   issue an error when a bad flag is given.
++#
++#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
++#
++#   NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG.
++#   Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS.

++#   Check whether the given FLAG works with the linker or gives an error.

++# SYNOPSIS
++#
++#   AX_REQUIRE_DEFINED(MACRO)
++#
++# DESCRIPTION
++#
++#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
++#   been defined and thus are available for use.  This avoids random issues
++#   where a macro isn't expanded.  Instead the configure script emits a
++#   non-fatal:
++#
++#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
++#
++#   It's like AC_REQUIRE except it doesn't expand the required macro.
++#
++#   Here's an example:
++#
++#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

+-		 * - in turn, the C runtime will unload libvips.so, the vips library,
+-		 *   since vips.so is the only thing that references it
+-		 * - libvips.so in turn uses glib.so, but this is often not unloaded,
+-		 *   since other parts of apache can be using it (glib could also
+-		 *   possibly be preventing unload itself, I'm not sure)
+-		 * - the main apache process then reloads vips.so, which in turn will
+-		 *   reload libvips.so as it starts up
+-		 * - vips.so tries to init libvips.so
+-		 * - libvips.so tries to register its types (such as VipsImage) with
+-		 *   glib.so, but finds the types from the previous init still there
+-		 * - everything breaks
+-		 *
+-		 * A simple fix that will always work is just to lock libvips in 
+-		 * memory and prevent unload. We intentionally leak refs to the shared
+-		 * library. 
+-		 *
+-		 * We include the binary API version number that this extension needs. 
+-		 * We can't just load .so, that's only installed with libvips-dev,
