UPX 3.08 executable packer

UPX is a portable, extendable, high-performance executable packer for several different executable formats, including Windows and Linux executables and DLLs. It achieves an excellent compression ratio and offers *very* fast decompression.

UPX 3.08 has been released. It is a minor 3.0x maintenance release to version 3 whose major additions were:

optional LZMA compression
support for BSD systems

Changes in 3.08 (12 Dec 2011):
* Fix allocation in runtime stub for darwin.macho-entry (i386 and amd64).
* Compress shared library on ELF i386 only [ld.so threatens even this case].
* Attempt to support ELF on QNX 6.3.0 for armel (experimental).
* Better diagnostic when ELF -fPIC is needed.
* PT_NOTE improvements for *BSD.
* Preserve more ELF .e_flags on ARM.
* Minor code improvements for ELF stubs.
* Defend against another flavor of corrupt PE header.
* bug fixes
