Shared lib build attempt on HP-UX 11.11

[Douglas Wilson]

The default build (with non-standard prefix) went fine, but I tried
compiling after "./configure --prefix=/users/test --with-shared"
and got:


       gcc -Ae -DHAVE_CONFIG_H -I../ncurses -I. -I. -I../include
-D_HPUX_SOURCE -I/users/test/include/ncurses  +Z -c ../ncurses/li
b_gen.c -o ../obj_s/lib_gen.o
