    * lib/python.c: Likewise.
    * lib/script.c: Likewise.
    * lib/sieve.c: Likewise.

    dbm_pagfno may be missing (on FreeBSD, dbm_pagfno expands
    to a non-defined macro, which produces compilation error.
    * mail/mailvar.c (mailvar_varptr_comp): Remove.
    (mailvar_list_copy): Use mailvar_variable_comp instead
    of the removed mailvar_varptr_comp.

    Add gnulib as a module

commit a41e62b9eb33c46ec0897c6c956057d8b797883d
Author: Sergey Poznyakoff <address@hidden>
Date:   Wed Jun 24 10:05:50 2015 +0300

    Make libmuaux installable shared library.
    
    This commit converts libmuaux into installable shared library that
    includes selected modules from gnulib.  Correspondingly,
    lubmu_argp is also converted into installable shared library, which
    is the main purpose of these changes.  This should allow other packages
    which depend on Mailutils to link against libmu_argp even on systems
    that for some reason choose not to include static libraries in their
    distribution (vide Debian).  Another side effect is that such packages
    won't need to bother about argp being present on the system, as it is
    now included in libmuaux.so.
    
    * bootstrap.conf: Don't create Makefile.am
    Build gnulib using libtool and use mu_am_flags custom module
    * lib/local/modules/mu_am_flags: New file.
    * configure.ac (MU_APP_LIBRARIES): Use libmu_argp.la
    (TCPWRAP_LIBRARIES): Add libmutcpwrap.a
    * lib/Makefile.am: Make libmuaux installable shared library
    New static library libmutcpwrap.a
    * libmu_argp/Makefile.am: Make libmu_argp installable shared library
    * examples/Makefile.am: Use libmu_argp.la
    * examples/cpp/Makefile.am: Likewise.
    * imap4d/Makefile.am: Likewise.
    * mapi/Makefile.am: Likewise.
    * mh/Makefile.am: Likewise,
    * pop3d/Makefile.am: Likewise.
