Exclude LZMA

If I compile an installer with zlib compression, does the binary output (install.exe) contain the LZMA decompression code even though it will not be used?

I ask as a client's legal department is stating that even with the license exception there are commercial distribution obligations of the LZMA binaries. I as a developer cannot see how this is the case given the wording but then I only deal in 1's and 0's.

My other option is to build the code from SVN without the LZMA code included. I then will have to deal with Legal on that matter as I would have potentially modified the NSIS code unless there is a config/makefile option to exclude it anyway.

Any help would be appreciated as I now may have to recode the installer in something else.

Thanks,

Makensis.exe contains code for all compression modes but the generated installer only contains code for one combination of zlib/bzip/lzma, solid/non-solid and ansi/unicode. You can see all of the base stubs in ...\NSIS\Stubs (12 in total for NSIS 3.0 32-bit)

The scons script also supports building only some of the stubs...
