Greetings

I am trying to compile swftools-0.92  an optional dependency of gnash (
http://www.linuxfromscratch.org/blfs/view/svn/xsoft/gnash.html ).
The computer has giflib5 (
http://www.linuxfromscratch.org/blfs/view/svn/general/giflib.html )
installed

Hi

Arch has a patch, i've attached it as it's only a fairly small one
Does that help?


regards

Martin
