 # Taken from mpfr-4.0.1, then modified for LDADD_FOR_TESTS_KLUDGE
 dnl Under Linux, make sure that the old dtags are used if LD_LIBRARY_PATH
 dnl is defined. The issue is that with the new dtags, LD_LIBRARY_PATH has
 dnl the precedence over the run path, so that if a compatible MPFR library
 dnl is installed in some directory from $LD_LIBRARY_PATH, then the tested
 dnl MPFR library will be this library instead of the MPFR library from the
 dnl build tree. Other OS with the same issue might be added later.

 dnl gl_THREADLIB
 dnl ------------
 dnl Tests for a multithreading library to be used.
 dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
 dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
 dnl default is 'no', otherwise it is system dependent. In both cases, the user
 dnl can change the choice through the options --enable-threads=choice or
 dnl --disable-threads.
 dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
 dnl USE_WINDOWS_THREADS
 dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
 dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
 dnl libtool).
 dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
 dnl programs that really need multithread functionality. The difference
 dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
 dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
 dnl Sets THREADLIB_CPPFLAGS to -D_REENTRANT or -D_THREAD_SAFE if needed for
 dnl multithread-safe programs and adds THREADLIB_CPPFLAGS to CPPFLAGS.
