And unfortunately, I consider this move in wrong direction, since inclusion of pregenerated prelude.c is more or less against Fedora's policy [2]. Yes, this paragraph is about pre-built binaries and libraries, but I believe that pre-generated code is the same in the same spirit.

And it shouldn't contain configure/Makefile, only configure.in/Makefile.in, making autoconf/automake a requirement for building.  Is it Fedora's policy to delete files generated by bison/autoconf/automake and regenerate them before compiling the software?  If not, why would prelude.c be any different?

I knew that somebody will ask this and I'll bite, why Ruby should be shipped in source form at all? Since everything Ruby user needs is binary.

So while some pre-generated code in source tarball allows to remove the BASERUBY need, which is appreciable, prelude.c is not (so far) the case. I'd be very happy if the amount of pre-generated code could be kept as low as possible.

I have no Ruby installed on my build machine. Last time I checked r48476, which was working just fine.
