This change will cause builds (by default) to not use different STACK 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.

This change will cause builds (by default) to not use different STACK 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.
