*lol* !

You could do something like --enable-have-a-lzw-license

But noone can control this so unisys would consider anybody
using php with gif a criminal. And i do not want to know what
they think about the development of php. MAybe they find a
solution to stop us because *we* are violating their patent in
any way.

As far as i know, only using the LZW Algo violates the patent, but not
having it on your harddisk, or?

Question...

Would it be illegal (patent violation) to add a compile switch to php...

--enable-gif-support-and-violate-the-unisys-patent

which activates the GIF support? We cleary say, that using it is a
violation...
As far as i know, only using the LZW Algo violates the patent, but not
having it on your harddisk, or?

It'll support LZW compression if you recompile it and the tiff libraries.

afaik, it supports uncompressed GIF, which is useless :). PHP bundled GD
supports read support for GIF, as far as you do not need to output GIF
images (mobiles) try to use png or others formats instead.
