[Emacs-diffs] master a5f8586 02/15: Link temacs with gnulib compiled with -Demacs

[Paul Eggert]

branch: master
commit a5f85861293911b3f394464a04f7972b83d47a95
Author: Wolfgang Jenkner <address@hidden>
Commit: Paul Eggert <address@hidden>

    Link temacs with gnulib compiled with -Demacs
    
    This is done to support HYBRID_MALLOC, since some static variables
    (e.g., last_environ in putenv.c) hold pointers to memory malloced
    before dumping (Bug#22086).
    * lib/Makefile.am: Add incantation to install libegnu.a.
    * src/Makefile.in ($(lib)/libgnu.a): Replace with libegnu.a
    (temacs$(EXEEXT)): Use it.
