    This change will cause builds (by default) to not use different STACK · e41c8d6a
    Geoff Thorpe authored
    structures and functions for each stack type. The previous behaviour
    can be enabled by configuring with the "-DDEBUG_SAFESTACK" option.
    This will also cause "make update" (mkdef.pl in particular) to
    update the libeay.num and ssleay.num symbol tables with the number of
    extra functions DEBUG_SAFESTACK creates.
    
    The way this change works is to accompany each DECLARE_STACK_OF()
    macro with a set of "#define"d versions of the sk_##type##_***
    functions that ensures all the existing "type-safe" stack calls are
    precompiled into the underlying stack calls. The presence or abscence
    of the DEBUG_SAFESTACK symbol controls whether this block of
    "#define"s or the DECLARE_STACK_OF() macro is taking effect. The
    block of "#define"s is in turn generated and maintained by a perl
    script (util/mkstack.pl) that encompasses the block with delimiting
    C comments. This works in a similar way to the auto-generated error
    codes and, like the other such maintenance utilities, is invoked
    by the "make update" target.
    
    A long (but mundane) commit will follow this with the results of
    "make update" - this will include all the "#define" blocks for
    each DECLARE_STACK_OF() statement, along with stripped down
    libeay.num and ssleay.num files.
