Clear message

There are still some programs that have executable stack regions.

open bugs in LP
check an ELF binary: "readelf -lW $BIN | grep GNU_STACK" shows with "E" flag.
Gentoo write-up of what to do: http://www.gentoo.org/proj/en/hardened/gnu-stack.xml
-Wl,-z,noexecstack will change the behavior of compiler's asm-without-stack-markings defaults.

Main/Restricted Packages

Originally generated from the ELF files with executable stacks in Karmic main.
