tuneup compilation error on Ubuntu 8.04.3 LTS

[Jernej Makovsek]

gcc 4.2.4, gmp 5.0 and gmp 4.3.2

after $gmp-5.0/./configure which finishes without errors:
$cd tune
$make tuneup
gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../tests    -O2 -pedantic
-m64 -mtune=k8 -march=k8 -c tuneup.c
In file included from tuneup.c:114:
../gmp-impl.h:102:23: error: fib_table.h: No such file or directory
../gmp-impl.h:103:22: error: mp_bases.h: No such file or directory
make: *** [tuneup.o] Error 1

don`t know what I`m doing wrong, It`s right out of the documentation.

Also where can I see what are "extremely large numbers" mentioned with the
the `-f NNN' parameter in the documentation? Are they10Mbytes large numbers
or 1Gb or 1kb? What does happen when I enter a small NNN value and use
"extremely large numbers"?

Sincerely,
Jernej
