patch: boost/function/function_template.hpp fails to compile with gcc -fno-exceptions

[andyc@…]

.... despite the fact that I've got BOOST_NO_EXCEPTIONS defined. Here's the error message:

.../boost/function/function_template.hpp:597: error: exception handling disabled, use -fexceptions to enable

The following patch fixes it but I'm not sure the #else part is correct:

Actually, there are two try/catch blocks to wrap with an #ifdef BOOST_NO_EXCEPTIONS block: one at line 564, the other at line 595.

(In [39061]) Handle GCC's -fno-exceptions properly. Fixes #1198
