Allow spl_config.h to be included by dependant packages (updated) We need dependent packages to be able to include spl_config.h to build properly. This was partially solved in commit 0cbaeb1 by using AH_BOTTOM to #undef common #defines (PACKAGE, VERSION, etc) which autoconf always adds and cannot be easily removed. This solution works as long as the spl_config.h is included before your projects config.h. That turns out to be easier said than done. In particular, this is a problem when your package includes its config.h using the -include gcc option which ensures the first thing included is your config.h. To handle all cases cleanly I have removed the AH_BOTTOM hack and replaced it with an AC_CONFIG_HEADERS command. This command runs immediately after spl_config.h is written and with a little awk-foo it strips the offending #defines from the file. This eliminates the problem entirely and makes header safe for inclusion. Also in this change I have removed the few places in the code where spl_config.h is included. It is now added to the gcc compile line to ensure the config results are always available. Finally, I have also disabled the verbose kernel builds. If you want them back you can always build with 'make V=1'. Since things are working now they don't need to be on by default. 2010-03-23 00:45:33 +03:00			`DEFAULT_INCLUDES = -include ${top_srcdir}/spl_config.h`
