* ccan: configure check for HAVE_BUILTIN_CHOOSE_EXPRRusty Russell2011-09-141-0/+15
| | | | | | | | | 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>
* ccan: fix configure tests for __builtin_clz etc.Rusty Russell2011-07-051-8/+8
| | | | | | | | | | 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.
