configure, build and file cleanup

configure, build and file cleanup

[William Tyler]

Hi all,
I would like to get familiar with the configuration and build system for
gcc.  I think that this would be a good place to start filtering out unused
files.
I think that I could also work on filling in the documentation in these
areas as well.  Does this seem like a reasonable aproach?

I hope that these questions are not too nubie like but here goes:
I have looked at the configure script and do not recognize it, where can I
get information on that is going on here (language, syntax and what not?)
Where can I get information on the make files and how they are processed?
Are the make files generated as output to from the configure script?

Thanks for the information folks.

Bill

If you mean the toplevel configure script, please ignore it for now.
It's being converted to autoconf format, like the other configure
scripts.

First, learn about autoconf.  Then, read the "source tree structure
and build system" chapter of the GCC internals document.

Yes, and from Makefile.in
