It appears cmake cannot even build on DJGPP.  I pass on this developer's
report of the problems he had with that build.

*************
The bootstrap script doesn't work. It makes a lot of assumptions about
filenames which aren't compatible with DJGPP~E namely it assumes you have
more than 8.3 characters. This falls down when the script tries to make
directories, which fail. Hand making the directories, you then get a fail
because it can't find the compiler, trying "cc" first, which causes DJGPP's
bash to crash when it can't work. Getting rid of all other compilers, and
leaving the only option as gcc, I end up with:

Try: gcc
Line: gcc  cmake_bootstrap_13401.test.c -o cmake_bootstrap_13401.test

After that, I tried boostrap --help, but it didn't work~E it just tries to
rebuild the test file, and I end up with the same stack dump.

So it isn't looking easy at this stage.

Unless someone here has some ideas, I think we will give up on CMake for
DJGPP.
