Wow not a minute later and I get bitten by my own solution. A C
function returned 1 for a supported feature, and -1 otherwise. And of
course -1 got converted to true, so then I had a bug in my code.
Damn silly C functions which return -1 when they should return 0.
Or damn me for not RTFM'ing.

It can't implicitly convert an int to a bool. The C function returns an int.
