7-Zip port more progress

[Seo Sanghyeon]

Cleaned up build system to include compiled file's
current directory. Needed to compile "Compress" directories.

Patched here and there.

154 files compiled, patches 66 lines. (-22, +44.) There are
345 files total in the source tree.

Now problem is that it seems wineg++ has problems with Wide
character functions. Not in C, but it seems in C++ libc headers
are included instead of msvcrt headers, resulting in compilation
failures. Is my analysis correct?

Current SConstruct configuration:

all = """
Common
Windows
7zip/Common
7zip/UI/Common
7zip/Archive/*
7zip/Compress/*
"""
exclude = """
7zip/Archive/7z
7zip/Archive/Cab
