Re: port freadahead.c & fseeko.c

Paul,

Mind, I'm I am cross compiling

So I cd-ed to:
/home/ron/novax-prs/tmp/work/x86_64-linux/m4-native/1.4.17-r0/build/lib/
and opened: ../../m4-1.4.17/lib/fseeko.c
but funny enough, I cannot find any function that is called "rpl_fseeko" 
even though the error states:
