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 =(
