-fexceptions
Enable exception handling. Generates extra code needed to propagate
exceptions. For some targets, this implies GCC will generate frame
unwind information for all functions, which can produce significant
data size overhead, although it does not affect execution. If
you do
not specify this option, GCC will enable it by default for
languages
like C++ which normally require exception handling, and disable it
for languages like C that do not normally require it. However, you
may need to enable this option when compiling C code that needs to
interoperate properly with exception handlers written in C++. You
may also wish to disable this option if you are compiling older C++
programs that don't use exception handling.
