Inline-0.52_02 released

Hi,

Only change is a small alteration to Inline::C::validate().
This is mainly for the benefit of Inline::CPP.

See:
https://rt.cpan.org/Ticket/Display.html?id=11748

Unless cpan-testers reports tell us that this change has broken something, 
it will be released as 0.53 early next week.

Cheers,
Rob
