configure: WARNING: CANNOT PROPAGATE EXCEPTIONS BACK FROM GMP:
*** MEMORY EXHAUSTION MAY RESULT IN ABRUPT TERMINATION.
*** This is OK, if you do not plan to use the bounded memory capabilities
*** offered by the PPL. Otherwise, if you are using GCC or the Intel C/C++
*** compiler, please make sure you use a version of GMP compiled with the
*** `-fexceptions' compiler option.
*** To build such a version, you can configure GMP as follows:
*** CPPFLAGS=-fexceptions ./configure --enable-cxx --prefix=/usr/local
