These two do not mesh, that is my point. In the case of class constants,
is it acceptable to simply check the PHP version number, or is there a
way (similar to, or using function_exists/class_exists) to check for the
specific functionality that I need.

like Otto mentioned before, you could check for PHP5 support before
allowing
the plugin to be activated.

Along these lines, is there an easy/safe way to check if a const
variable in a class will be accessed properly, versus throwing a fatal
error? It seems like some_method(ClassName::CONST_VAR); will throw a
fatal error in PHP 4 (I'm assuming because class constants are not
supported in 4). So, instead of checking for PHP version 5 or greater,
how would I check specifically for constant variable support?
