No, those are for lines like this:

  GL_GENERATE_ALLOCA_H = @GL_GENERATE_ALLOCA_H@

Yes, I think the problem is that you are building from the repository.
You should build a pretest tarball instead.  The support for building
from the repository was not tested in many years, and has probably
bit-rotten quite a lot.

The tarball shouldn't have the msdos/autogen/ directory.  It does have
it now, but that is a mistake.  So unpack the tarball and delete
msdos/autogen/ with all its contents, then try again.
