Make the code compile warning-free:

- declare a dummy "struct timezone" for some Win32 systems (MinGW)
- fix a few printf() argument types
- get rid off the prevailing "all filedescriptors are of type int"
  attitude

The last item required a large sweep across the code, in order to
replace all "int fd"s by "struct filedescriptor *fd"s, and pass
pointers (as we cannot pass a union directly).  In return, the
code is now supposed to be fully 64-bit safe, rather than relying
on a 64-bit pointer being converted to a (32-bit) int and back
to a pointer as we did previously.
