tcsh-6 compilation error with gcc44 (buildworld)

[Saifi Khan <saifi.khan@xxxxxxxxxxxxxxx>]

Hi:

On a AMD64X2 system running DragonFly v2.5.1.187.gc1543-DEV

i'm trying to 'buildworld' with 'gcc44' as

# CCVER=gcc44 make buildworld

. ..
. ..

In the code as can be see here,
http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/contrib/tcsh-6/gethost.c

. ..
 char defs[INBUFSIZE];
. ..
. ..

 case T_NONE:
    if (state != S_CODE && defs && *defs != '\0') {
    ...
    }
. ..

The expression seems fine to me. 
Any workaround for this ?


thanks
Saifi.
