-# This file provides several macros to use the various Boost libraries.
-# The first macro is BOOST_REQUIRE. It will simply check if it's possible to
-# find the Boost headers of a given (optional) minimum version and it will
-# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to
-# your configure so that users can specify non standard locations.
-# If the user's environment contains BOOST_ROOT and --with-boost was not
-# specified, --with-boost=$BOOST_ROOT is implicitly used.
-# For more README and documentation, go to http://repo.or.cz/w/boost.m4.git
-# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,
-# simply read the README, it will show you what to do step by step.

-dnl Optimization hacks: compiling C++ is slow, especially with Boost. What
-dnl we're trying to do here is guess the right combination of link flags
-dnl (LIBS / LDFLAGS) to use a given library. This can take several
-dnl iterations before it succeeds and is thus *very* slow. So what we do
-dnl instead is that we compile the code first (and thus get an object file,
-dnl typically conftest.o). Then we try various combinations of link flags
-dnl until we succeed to link conftest.o in an executable. The problem is
-dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
-dnl remove all the temporary files including conftest.o. So the trick here
-dnl is to temporarily change the value of ac_objext so that conftest.o is
-dnl preserved accross tests. This is obviously fragile and I will burn in
-dnl hell for not respecting Autoconf's documented interfaces, but in the
-dnl mean time, it optimizes the macro by a factor of 5 to 30.
-dnl Another small optimization: the first argument of AC_COMPILE_IFELSE left
-dnl empty because the test file is generated only once above (before we
-dnl start the for loops).
