Best save and restore the current position, as well.

Might also want to make things "long" just in case someone compiles it under
old Manx. Or to be really minimalist:

#define filelength(fh) Seek(fh, Seek(fh, 0L, OFFSET_END), OFFSET_BEGINNING)

(oddly, my old DOS manual defines both OFFSET_END and OFFSET_BEGINNING as 1)
