What library provides the uio.h header file?

Hi. uio.h is a POSIX system file, cononically sys/uio.h, but include/sys is also searched by many compilers so uio.h tends to work. I'm working on a PR to FFS that will enable builds on windows and which fixes this and many other issues. I should be merging that soon, but if you don't want to wait you can simply change this line to include sys/uio.h rather than simply uio.h.
