Is this why my XCB calls on Linux fail? I already accused XCB people of writing
incorrect tutorials until I realized that the exact same code does work in C.
After probably two hours of trial and error to fix my code and reading articles
on the web the word x86-64 showed up there and I had a dim memory of something
not working in DMD 64-bit and C structs. So I tried GDC again, which I stopped
because it produced another error somewhere else. There it works. The struct I
try to get returned by a C library function looks like this:

struct { void*, int, int }

Most notably the int fields in my case should be 116 and 1, but are 0 and 0,
while the pointer does have some value (not sure if the correct one as they
change from executable to executable).
