421 dnl Optimization hacks: compiling C++ is slow, especially with Boost. What
422 dnl we're trying to do here is guess the right combination of link flags
423 dnl (LIBS / LDFLAGS) to use a given library. This can take several
424 dnl iterations before it succeeds and is thus *very* slow. So what we do
425 dnl instead is that we compile the code first (and thus get an object file,
426 dnl typically conftest.o). Then we try various combinations of link flags
427 dnl until we succeed to link conftest.o in an executable. The problem is
428 dnl that the various TRY_LINK / COMPILE_IFELSE macros of Autoconf always
429 dnl remove all the temporary files including conftest.o. So the trick here
