<br>
If it's the right thing to do, please send a patch to invert the logic here, so that we check for make before checking for IgnoreErrors.<br>

Thanks!<br>

> I was having some trouble getting scan-build to scan my C code when running make, so I looked into the perl and saw that I need to pass the -k flag to scan-build to override the CC variable. Is this the intended behavior? The docs make it sound like -k is just there for convenience, but none of the examples with make show manually overriding CC when not passing -k. This is happening with checker-275, but the version in svn has identical logic around 'AddIfNotPresent($Args, "CC=$CCAnalyzer");'<br>
