Come on, have you ever seen a project that worked like that ?
Seriously, "show me the code" is the motto of any project with more
than a handful of people, unless you are paying money.

I would be interested in trying out any patches you made that removed
the glib dependency.  If two people where using it regularly and
merging in the other continuing changes, Pavel might be more
interested.  Even if you only remove some of the dependencies, maybe I
can see about the remaining ones.

I like the idea of writing very simple, but safe and bug-free, code
that depends on as few libraries as reasonably possible.

I'm ldd'ing mc 4.6, to show you that the total number of library
dependancies in my version.  Perhaps you might check your version and
see if there are library dependancies other than glib that can be
removed by changing the parameters to ./configure.

No, and I wasn't implying that it did.  However, it is likely that you
can do far more shrinking of your mc by applying a few configure flags
(even if glib is still there) than you would get by removing glib,
which would require writing code.

On slackware 8.1 glib is 171k.  On Debian 3.0 it is 138k.  On Debian
testing it is 400k -- that's because it glib 2.0.

To get rid of a dependency on a 400k binary (glib 2.0) I would start
writing code, so I begin to see your point.  I probably would not do
it for the glib1.2, simply because I know of other trickery I can
employ to save me that much space, mainly removing stuff from the
linux kernel.

Why don't you see if you can use glib 1.2 ?  Then you can save a lot
of space without much work.  I have been able to compile mc 4.6 on
linuxes that had only the 1.2 version of glib, so I suppose the
configure scripts pick that up automatically.
