If square_func is not valid C or C++ syntax then the same property of invalid
C/C++ syntax should apply to

extern int fcloseall(void) __THROW;

 which should expand to

extern int fcloseall(void) throw();

When I declare square_func(int) as

int square_func(int) __THROW;

then the code compiles fine with gcc

My question is according to the 'C' language valid forms of function declarations are:

<storage-class-type> <return-type> <function-name>(<parameter type list>);

But then

extern int fcloseall(void) __THROW;

does'nt seem to fit into this syntax.

If terms like __THROW are allowed then is it possible to use custom defined
macros like __SNODX? If only a set of reserved terms are permitted as m pointed out
then where is the list of these terms?

Thanx in advance.

Eagerly awaiting responses.
