+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.
