at compile time using the -DAP_MAX_INCLUDE_DIR_DEPTH switch.
PR 28492. [André Malo]

*) mod_setenvif: Remove "support" for Remote_User variable which
never worked at all. PR 25725. [André Malo]
*) minor mod_auth_basic and mod_auth_digest sync. mod_auth_basic
now populates r->user with the (possibly unauthenticated) user,

PR 14223. [André Malo]
