Re: --with-modules on HP-UX 10, 11 (fwd)

[Gary V. Vaughan]

Hi Bob, Albert,

Thanks for the backtrace... I see what is happening now.

  argz_insert(&argz, &len, NULL, entry) == argz_add(&argz, &len, entry)

I have a pet hate of API calls that perform several entirely different
tasks based on the contents of an argument.  If there are 2 tasks to be
performed, it is easier to write correct code when each has its own
call.

I had intended to force the programmer (me!) to use argz_add when
appending and argz_insert when inserting... glibc's argz implementation
doesn't enforce this, so I should have used these asserts at the
lt_argz* layer.  Otherwise glibc platforms never run the check, and
hence I didn't see the buglet in my code because I develop mostly on
GNU/Linux.

Patch to follow...

Cheers,
        Gary.
