I am building binutils 2.14 on native ia64-hp-hpux11.22
(available through HP's test drive program).  I'm getting these
warnings when I build 'ar':

  cc -Wp,-H256000 -g -o ar arparse.o arlex.o ar.o not-ranlib.o arsup.o rename.o
  binemul.o emul_vanilla.o bucomm.o version.o filemode.o  ../bfd/.libs/libbfd.a

  13 warnings.

The resulting 'ar' does not execute.

A little investigation shows that ia64-hp-hpux11.22 and
ia64-hp-hpux11.23 have a problem:

  % cc hello.c -ll
  ld: (Warning) Unsatisfied symbol "yyleng" in file /usr/lib/hpux32/libl.so
  ld: (Warning) Unsatisfied symbol "yylenguc" in file /usr/lib/hpux32/libl.so
  ...

  % cc +DD32 hello.c -ll
  ld: (Warning) Unsatisfied symbol "yyleng" in file /usr/lib/hpux32/libl.so
  ld: (Warning) Unsatisfied symbol "yylenguc" in file /usr/lib/hpux32/libl.so
  ...

  % cc +DD64 hello.c -ll
  ld: (Warning) Unsatisfied symbol "yyleng" in file /usr/lib/hpux64/libl.so
  ld: (Warning) Unsatisfied symbol "yylenguc" in file /usr/lib/hpux64/libl.so

This problem does not happen with hppa-hp-hpux11.11.

I worked around the problem by nulling out LEXLIB before
running configure:

  export LEXLIB=" "
  /.../.../configure ...
  make
  make install

This causes the configure script to skip the test for LEXLIB
and just use a blank value rather than the normal value of "-ll".

'ar' and the other binutils programs don't actually need "-ll",
because they carefully define their own yywrap().

I don't know what the right fix is.  You might want to boot the problem
upstream to the autoconf guys.  Meanwhile, I'll keep plugging ahead with
this workaround.
