Why do X .debs take so much damn room to build? (was: Pentium Optimized)

I'm pretty sure the #1 reason for this is policy 4.1, which mandates the
usage of "-g" as a CFLAG.  In hamm, slink, and earlier, X wasn't built with
this.

By the time the process is done, you have the following situation:
1) post-compilation X source tree (loads of unstripped stuff)
2) debian/xtree, which contains the complete set of files installed by the
   X make process (loads of unstripped stuff)
3) the package build directories, which contain almost all the stuff from
   2), cp'ed...not mv'ed (stripped stuff)
4) the finished .debs sitting above the source tree (stripped, compressed
   stuff)

Even worse, i386 and m68k add libc5-compiled X libraries, which result in
smaller (but substantial) versions of 1-4 above.

Even with all this bloat and redundancy, in slink days you could build X in
about half the space it now requires.

Mind you, I'm not advocating the reversal of the -g policy.  Just trying to
explain why an X build takes so damn much space.
