No, you should'n worry about it if you get your files
onto unix in their original names (minus extra chars).
Kernel takes care of that when script asks for big f-name
it truncates it the same way as it did when you untar it
there. Problem may arise if you go thru DOS. Then you
must take care that upon getting it to Linux you should
get them back to original names (or first 14 chars of
that).

Thirst You must (should) have gcc 2.2.2 instaled.
As far as my memory serves me:
1) include files will go into /usr/inlude plus subdirs.
2.2.2 include will be erased. You should take care about
setjmp.h as described in release (or FAQ) note.
2)libraries will go to /usr/lib/gcc-lib/i386-linux/2.2.2d
You should also get include, jump and shared subdirs
there.

It untars it puts it into rights places, removes old
compiler( ie its includes and binaries) links
/usr/src/linux/include with /usr/include/linux, creates
/usr/lib/gcc-lib/i386-linux/2.2.2d/specs containing
ver #.

No, I dont think so. It checks for dirs. Some of them
should'nt be there (like /usr/lib/gcc-lib/i386-linux/2.2.2d)
so it will fail on its existance with error message. It
doesn't check if files are in right places 'cause it puts
them there. But you should read all docs (readme, FAQ and
all 2.xx realease notes) couple of times before
installing it. You must have .97plx sources on line and
you should have gcc 2.2.2 installed.(you will need it
anyway).

-nostdinc is a flag that tells compiler (actually a
preprocessor) not to look in std include dirs (defined
inside compiler) but in dirs specifide on command line.
You should remove it from Makefiles (actually only one in
/usr/src/linux) because include files from compiler and
the kernel are now consistent.
Make is a utility that automates compiling large (and
small) projects which come in number of source files. You
should have it in /bin or /usr/bin on root disk. If not
look for it in tsx-11.mit.edu (pub/linux/binaries/usr.bin
I think).
Make reads Makefile for instructions. You should learn
how to use it even if you dont plan on learning C.Almost
all software in Unix world comes in sources with
makefiles. Read man make on your Unix machine.
>-  where I find gdb
Should be on tsx-11. Maybe you can wait. Someone is
getting ver 4.6 to compile.

why would you? But then it is no problem. Just mv it and
create a symlink form /your kernel src/include to
/usr/include/linux if you already installed gcc 2.2.2d or
tell instal.2.x right directory. Also you will have to
tell it to ps package - read readme there.
