samba - Feb 2004 - SIG_ATOMIC_T make error

I'm trying to compile Samba 3.0.0. using gcc 2.95.3 and the make fails with
the
following errors:

In file included from include/includes.h:761,
                 from dynconfig.c:21:
include/../tdb/tdb.h:130: parse error before `*'
In file included from include/includes.h:896,
                 from dynconfig.c:21:
include/proto.h:6460: parse error before `*'
*** Error code 1
make: Fatal error: Command failed for target `dynconfig.o'

The lines in tdb.h and proto.h that cause the parse errors
are identical, and contain the following definition:
 
void tdb_set_lock_alarm(sig_atomic_t *palarm);

Please can someone suggest where this is failing?

Thanks,

Julian
