FWIW, clamav-0.94.1 does not compile under 5.X without
CONFIGURE_ARGS+--disable-gethostbyname_r.  When compiled this way it does not
run (exits
after initialization with no error logging).

Though 5.X is no longer officially supported there are many sites still
running it which could benefit from a patch, assuming it would be trivial
to create such a patch.

One more patch needed:
sed -i '' -e "s/enable-gethostbyname/disable-gethostbyname/;
/^PTHREAD_LIBS/s/lthr/lpthread/" Makefile

(replace lthr with lpthread which has proven unstable in clamav anyway)

I have several legacy 5.5 systems running this way.
Note: unofficial, not supported by me, SECNAP, Freebsd, the RNC, the DNC, or
the free masons. YMMV
