Fails to build on HP-UX 10.20

[Matt Kraai]

Howdy,

When I try to build bash 4.0 on HP-UX 10.20, it fails with the
following error:

          cc -Ae -L./builtins -L./lib/readline -L./lib/readline -L./lib/glob  
-L./lib/tilde -L./lib/malloc -L./lib/sh    -g -o bash shell.o eval.o y.tab.o

-ltilde -lmalloc lib/intl/libintl.a
 /usr/ccs/bin/ld: Unsatisfied symbols:
    _ (code)
 *** Error exit code 1

Using nm, I found that _ was undefined in siglist.o.  If I include
bashintl.h in siglist.c, the problem is fixed.
