Description:
        Problem compiling siglist.c on HPUX (error about undefined symbol _ at 
link time).

Repeat-By:
        Execute a regular build sequence (./configure; make all) on a 
hppa2.0w-hp-hpux11.11 machine.

Fix:
        #include "bashintl.h" within the #if...#endif (for example, just after 
#include "xmalloc.h").
        I suppose Makefile.in has to be updated for siglist.o dependencies as 
well.
