[warning: implicit declaration of function] if enable flag std=c99

[Salvatore Santagati <salvatore dot santagati at gmail dot com>]

Hi

I've tried to compile a source code[1] with this flags
"-D_FILE_OFFSET_BITS=64 -pedantic -Wconversion -Wpointer-arith
-Wcast-align -std=c99" and output is

lfs.c: In function 'main':
lfs.c:26: warning: implicit declaration of function 'fseeko'
lfs.c:28: warning: implicit declaration of function 'ftello'
