Suggestion: Exception Support

Suggestion: Exception Support

[Tommy Nordgren]

I suggest that the configure script should be set up so that make will  
build the GSL
library with C++ exception support if possible. (C code must be  
compiled with the flag
-fexceptions under gcc) I've noticed that configure don't turn on this  
flag by default.
(If a c library is NOT compiled with -fexecptions, any exception  
thrown across a c function call
on the stack, will always terminate the application)

Thanks for the suggestion.  It probably would be more convenient, but
changing the autoconf defaults tends to cause unexpected problems so I
prefer to stick with them.  

I'll add a note in the INSTALL file to make the -fexceptions option
more prominent.  Presumably most distributions should be adding this
anyway.
