I also had this problem when I compiled 2.2.1 on my FC4 machine.  I solved this by including  "Scanner.h.in" in Scanner.l  Hope this help.

Hi wcliao,
thanks for the hint. Worked for me too.

EDIT:
Well, looks like i now have the same problem like alantang888. Compilation worked with adding the include but linking fails for the same reason.

I had the same problem on a Mandriva system.
I thus checked the version of Flex that I had and it was 2.5.4a
I upgraded it to 2.5.35 and the error did not go away while compiling. I thus edited the Scanner.l file and applied the suggested patch.
It compiled just fine and the link worked like a charm.
Thus I would suggest upgrading the requirements in configure to force having a version post 2.5.4a and add the fix in Scanner.l

Regards

EDIT: this was trying to compile the aMule 2.2.1 tgz archive content, no source repository content at all.

yeah!!! youpla's way is WORK!!!!! update flex to 2.5.35+ wcliao 's way "including  "Scanner.h.in" in Scanner.l" is success to make & install!!

flex 2.5.35 rpm:  ftp://ftp.uni-bayreuth.de/pub/redhat.com/fedora/linux/releases/9/Everything/i386/os/Packages/flex-2.5.35-1.fc9.i386.rpm

I had this same problem too, except on Suse 9.3.

Like the others above I added the following line to  ../src/Scanner.l

#include <Scanner.h.in>

and that fixed it for me too ..
