 # This is a utility that searches out "DECLARE_STACK_OF()"
-# declarations in header files, and updates/creates/replaces
-# the corresponding macro declarations that follow it. The
-# reason is that with "DEBUG_SAFESTACK" defined, each type
-# will generate 19 functions, all type-safe variants of the
-# base "sk_***" functions for the general STACK type. Without
-# DEBUG_SAFESTACK defined, we need to macro define all the
-# "type'd sk_##type##_***" functions as mapping directly to
-# the standard sk_*** equivalents. As it's not generally
-# possible to have macros that generate macros, we need to
-# control this from the "outside", here in this script.
