Makefiles for Mintlib / Finger(d) / Gcc questions

Subject: Makefiles for Mintlib / Finger(d) / Gcc questions
From: "J.D.Coleman" <J.D.Coleman@newcastle.ac.uk>

I found the existing Mintlib makefile very annoying when trying to compile
more than one variant of the libraries (e.g. normal and -mshort).  Deleting
all the objects and rebuilding everything just for one or two small changes
is very frustrating (not to mention time consuming!).

I have rewritten the Makefile and mincl (I called it Make-include instead)
to build each variant in a separate subdirectory, using Gnu make's VPATH.
Now, after changing one source file, I can have multiple variants installed
in no time at all.  I've appended the files below.

As MintOS doesn't have a real finger, I've ported the NetBSD version (fairly
simple).  I've put sources/diffs and 020+ binaries on :

	aire.ncl.ac.uk:/pub/Atari/Binaries/finger*
	aire.ncl.ac.uk:/pub/Atari/Sources/finger*
	
	http://aire.ncl.ac.uk:80/Atari/Binaries
	http://aire.ncl.ac.uk:80/Atari/Sources

For gcc 2.6.3, what version of ld should I use?  I have an old version
from the (bin?)utils 3.6 which doesn't understand libc.a and keeps looking
for gcc.olb instead.  Can someone point me at an ftp site?  Thanks.

Finally, which version of gcc do I need for it to recognise -G?

Thanks,

J
