162 request information to the request_rec structure. [Daniel Gruno]
164 *) mod_lua: Add a server scope for Lua states, which creates a pool of

196 [Matthew Steele <mdsteele google.com>]
198 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will

200 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
201 PR 51257. [Guenter Knauf]
203 *) core: In maintainer mode, replace apr_palloc with a version that
