No `int64_t` on FreeBSD (`__int64_t` seems to work)

[yggdr]

Not a C programmer, so I'm probably just doctoring around on symptoms instead of the underlying problems, but on FreeBSD gcc and clang complain about the unknown type name int64_t. Clang mentioned did you mean '__int64_t' in its error message, and a sed later (which only changed type.h) I compiled and seems to work on the cli :)

I wasn't much of a C programmer when I started this either. It's defined in stdint.h (not stdlib.h) but some compilers allow it without stdint.h just to be confusing.
