This is really not the best way to do it. Instead do like this:

 1. [check out the modules as above]

 2. mkdir build-dir

 3. cd build-dir

 4. ../tools/configure

    [answer to which target you want to build]

 5. make

It takes away the need of all manual editing of makefiles etc.

It is not a good idea to run the configure script in the actual tools
directory, and I believe that I will soon add some checks that will in fact
warn users about this and possible refuse to do it!

The reason why this is bad is that there already is a Makefile in that
directory, that is used for building the scramble tools etc. Having a
separate build directory also makes it easier to build for multiple platforms
and it makes it easier to remove all output files when you want to etc.

Tough question. I'm not really sure.

This is the instruction linked to from the daily-build page:

Oh? What uses memcmp()? We should not rely on any external libc-like library
(we've recently worked hard to remove the newlib dependency) so if we need
memcmp() we should provide our own.

It was because you had configure overwrite the makefile in the tools
directory that otherwise would've built it.

I think you're seeing the improvments by Eric Linenberg, the Sokoban map
levels are now a lot smaller.
