[exim] Exim-4.51 compilation error on FC4

I recently made a test install of Fedora Core 4 system, on x86 platform.

While compiling exim, I keep getting the errors pasted below. The minimised
way to reproduce the problem is to

- unpack the tarball
- copy /src/EDITME to Local/Makefile

- change Local/Makefile as follows:
-- EXIM_USER=ref:exim
-- eximon compilation suppressed (# added to a proper line)

- make

Exactly the same procedure compiles without problems on up-to-dated FC3
system.

- Anyone else met this?
- any ideas what to do?


Regards,
Timo
