I wish there is somebody to port this.
As per Igor Standalone command line version in folder

I made a try at it, once.. but it has lotsa subdirectories and
libraries... without working Makefiles is not-so-easy to figure out
how to compile.
Moreover the source code is written so "Windows-like" (and I know *no*
Windows programming) that I can't understand which part of the code is
Windows-specific and which one just uses Windows names for "normal
OK, I didn't know that .dsp could be translated "easily" to Makefiles (I
can't find any program that does so *and* works, though) but fortunately
Filip knew it and did a "unsupported" patch.
I upgraded that to apply to 7-zip 3.11 clean source (using cygwin in
-mno-cygwin mode, while his patch used mingw) so that a 7za.exe "stand
alone executable" can be created with cygwin's gcc.
As Biju said in an earlier message, this is at least the beginning...
BTW: 7za.exe is much more like zip.exe than gzip.exe, as it is an
archivier, not simply a compressor.
Could be interesting to "extract" a compressor from it, and maybe adapt
tar to use it, too.
PS: strangely enough, the file is much much bigger (almost the double)
and also a little slower (even if using -O3 -march=i686 it is 2x size an
10% slower than the original anyway)
I don't want to believe that VisualC is better than gcc-3.3 =(
