Comment:

 This is not a bug, as such - or rather, it's a bug in the via-C backend
 that it actually works when compiling with -fvia-C (we fixed this recently
 in HEAD).  The FFI is defined to interface to the C ABI rather than the C
 API; it doesn't take account of CPP magic.

 To work around this you typically need to call a C wrapper via the FFI
 rather than calling the C function directly.  The C wrapper lives in a .c
 file and gets compiled by the C compiler.  We have lots of these scattered
 about the libraries already.
