999b80bbb8 Buffer overrun: Fix false negative 2011-08-07 17:54:25 +02:00

cfcfa3f000 Use "enabled" list for the style checking. 
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

7f9dc42ff1 Fix test array_index_24() to share code with environments where plain char is either signed or unsigned. 
This was done, because that particular test has been already fixed a couple of times and it is still broken in some systems.
