I haven't seen this problem, but for a wild guess, are you using dbm
from a system library? gcc and cc differ on their convention for
returning dbm structs, and programs that use dbm should either use the
-fpcc-return option on gcc when compiling, (may not work in gcc
versions before 1.35, I think), or compile a version of
dbm/sdbm/gdbm/dbz/whatever with gcc and use that.

This also applies to any other routines that return structs, rather
than pointers to structs.

[Geoff Collyer also warns that you had better use gcc -traditional --
 he staunchly denies that C News is written in ANSI C, and insists
 that compiling C News with an ANSI C compiler (alleged or otherwise)
 will void your warranty...]
