Hi,

Here is a little patch to fix a compiler warning

fixes:

lib/rational.c:62: warning: data definition has no type or storage class
lib/rational.c:62: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL'
lib/rational.c:62: warning: parameter names (without types) in function declaration

Oh yes, we didnt use it with modules up to now.
Thank You for the fix.

Note this has nothing to do if the symbol is used in modules or not.
It's just that EXPORT_SYMBOL (which publishes the symbol to the module
linker). I havn't checked, but I assume the compiler interprets

EXPORT_SYMBOL(rational_best_approximation);

just as declaration of a function EXPORT_SYMBOL and doesn't generate the
needed magic to actually export rational_best_approximation.

Best regards
Uwe
