Subject: [PATCH 3/5] build: make wafsamba CHECK_SIZEOF cross-compile friendly
|
|
|
|
Use the same trick as commit 0d9bb86293c9d39298786df095c73a6251b08b7e
|
|
We do the same array trick iteratively starting from 1 (byte) by powers
|
|
of 2 up to 32.
|
|
|
|
The new 'critical' option is used to make the invocation die or not
|
|
according to each test.
|
|
The default is True since normally it's expected to find a proper
|
|
result and should error out if not.
|
|
|
|
Status: Upstream.
