mechanism more flexible, but otherwise should not affect your build even if you regenerate the "configure" script. (Most likely you need to run bootstrap.sh as you really need to re-run autoheader for reasons that i do not completely understand). If you don't regenerate "configure", of course you will see no difference. In detail: - restructure the check for mandatory modules to remove some redundant code blocks; - extend the AST_EXT_LIB_CHECK so that it can used also for checking headers; - define the AST_C_DEFINE_CHECK macro to test for #defined symbols; - for the two above macros, add a last argument that getscopied into HAVE_$1_VERSION so the source can adapt to different versions of the same libraries/header/etc - document the above; - document a problem that existed before and i did not manage to solve: the 'description' argument to AC_DEFINE does not substiture shell variables so you will not see the actual values in the comments (in autoconfig.h).. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@44467 65c4cc65-6c06-0410-ace0-fbb531ad65f3
