Patch upstream rejected our last mkstemp patch, saying that tmpnam and mktemp 
were being used in a safe way. If Patch won't build with gcc-4.6, I suggest 
you check if it has already been reported, and if not then report it to the 
GNU project.

Fedora probably has a patch for this. You can check with them too. I lost the 
url for their patch archive.
