never used dmalloc and completely untested, but what about:

ADDITIONAL_CFLAGS="-DENABLE_DMALLOC" \
ADDITIONAL_LDFLAGS="-ldmalloc" \
./configure ...

The ADDITIONAL_* environment variables can be used to pass flags that are used
during compilation, but not for configure checks.

Fwiw, removing cc samba users mailing list from cc.
