License concerns

There are some concerns expressed in the slashdot discussion forum about the new license scheme. One AC writes --------------------------------------------------------------- I'm using PHP3 (and liking it very much), and some of the new PHP4 OO features sound very nice and really useful. But unless PHP4 may also be used under the terms of the traditional GNU GPL, I can no longer use GDBM with PHP (which I also do a lot). --------------------------------------------------------------- GDBM is licensed under GPL, so it might be the case that linking with non-GPL code (such as PHP4) is prohibited (that's what the LGPL license is for). Which other extensions libraries are licensed under GPL? -- Regards, Sascha Schumann Consultant
