They are.  Cheer up and read on.

Wrong start.  That batch file shouldn't be executed at all.  You should 
only do what MAKEGDB.BAT tells you to do.

Autoconfigure won't run on MSDOS, because it requires a Unix shell (and 
uses its features *heavily*).  Don't even think about it.

That's what you need to do.

What Make do you use?  Is it from DJGPP?  I think GNU Make defines $CC to 
be gcc by default, so you needn't edit the makefile (although it doesn't 
do any harm).

You should set LFN=n from the DOS prompt.  I think this problem (and
possibly also others) are caused by the fact that Make is trying to
support long filenames (aka LFN) under Win95, but the current DJGPP port
of GNU Make is not LFN-clean, and thus fails (although most DJGPP programs
do support LFN).  To correct this, type this from the DOS prompt BEFORE 
you begin building GDB:

	set LFN=n

and press [Enter].  Then repeat all the steps (and maybe unzip GDB 
sources again, in case you did something during your attempts that won't 
let it build).

Yes, it does.  It tells you to ``Alter makefile.dos if you want''.

I did everything like MAKEGDB.BAT says (I didn't run the .bat file, I did 
manually everything it says), and it worked like a snap.  The only 
differences are that (a) I didn't do it under Win95, and (b) I didn't 
give up ;-).
