patch files for PEAR

a few patch files based on trying to run with the Web frontend. some undefined variables, some errors that needed more info. if you like them, they're yours. a general comment: a while ago, someone proposed to internals a php.ini setting for disabling the '@' error-suppression mechanism. he basically got hooted out of school, but i am beginning to see what he meant. the @ thing is at least close to being overused. it's become like duct tape. in trying to make things work with PHP 5, whenever there was a problem, i would frequently have to remove layer after layer of error suppression until i found out what wasn't working. or using it to avoid undefined index errors. i mean, that works, but hmm. if the idea is to avoid displaying errors to the user, then maybe just temporarily turning off 'display_errors' with ini_set() or something? then you'd get the messages in the error log. i don't know, but some kind of "show me what's going on" mechanism would be helpful. anyways. just something to think about.
