[TYPO3-core] RFC: Fix bug when comparing version numbers

[Franz Holzinger]

Hello Karsten,

I think this will not work in all cases.

E.g. take sr_feuser_register 2.5.0 from TER.

	'dependencies' => '',

	'constraints' => array(
		'depends' => array(
			'cms' => '',
			'static_info_tables' => '2.0.0-',
			'php' => '2.0-',
			'typo3' => '',
		),
		'conflicts' => array(
		),
		'suggests' => array(
		),
	),


( I have only manipulated the version numbers for testing).

This code would not get reached as soon as dependencies is empty. However there are contraints-depends of which the version numbers should get converted.


Or is this an error and dependencies must be filled in?

But I think this error comes from TER, which empties the dependencies.
