* s3:build(autoconf): fix "no AC_LANG_SOURCE call detected" warningsMartin Schwenke2012-06-051-36/+36
| | | | | | | | | | | | | Autoconf 2.68 NEWS says: ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and AC_RUN_IFELSE now warn if the first argument failed to use AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have a compelling reason why you cannot use AC_LANG_SOURCE but must avoid the warning. Signed-off-by: Martin Schwenke <martin@meltin.net>

| | | | | | | | | We weren't testing for this, and without it, typesafe_cb just casts its function argument. This is why I didn't get a warning when one of my patches amended a function incorrectly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | It's not enough to compile-test them: Michael Adam points out that nonexistant functions merely cause a warning. We have to try to link them.
