Strictly speaking there's the C and POSIX rule that you can declare and
call a function yourself without including the relevant header, which
doesn't work with redirects in headers. But that only applies *if the
function declaration doesn't need any type defined in a header* (so is
only an issue for a few LFS functions, and not at all for the 64-bit time
functions). If desired that issue could be addressed by having a header
using "#pragma redefine_extname" which you could include from the command
line with -include.
