Description

The original Google Android NDK doesn't provide the swab function, so I defined my own. After migrating to Crystax, I got the "conflicting declaration of 'void swab(const void*, void*, ssize_t)' with 'C' linkage" error. So I removed my implementation and compilation succeeded, but now linker can't find the definition for this function.

P. S. I "fixed" the error by making my definition extern "C", but I still wonder if there's something missing in the NDK itself. Or, if swab is being declared by mistake.

Yes, this is bug. @swab@ is declared in system headers but not implemented. I'm going to fix it. Thank you for report.
