I agree that Alex Colvin describes a good way. But I would use Eli, which
offers a lot of help for source-source compilation. Here is a
german link of Eli, but in ftp.cs.colorado there is an Eli link too.
There I don't know the exact directory.


ftp://ftp.uni-paderborn.de/unix/eli


The Eli team distributes an ANSI-C grammar for Eli. Furthermore Eli is able
to generate from this grammar (automatically) an Eli-specification for a
C-C compiler, which will be a very good starting point.
