The way to tell GDB to stop at rename is "break rename".  (I suggest a
quick glance at the GDB manual, and also the built-in "help" command
could help ;-).

However, to debug this efficiently, you will need to rebuild
stubify.exe so that it has the debugging code for the library
functions as well.  To this end, you should do the following:

  - Download v2/djlsr203.zip and extract the following files from it:

	     src/stub/stubify.c
	     src/libc/ansi/stdio/rename.c
	     src/libc/ansi/stdio/_rename.c
	     src/libc/ansi/stdio/remove.c

  - Put all those files together on a single file and call that file
    stubify.c.

  - Compile that file like this:

	    gcc -Wall -O -g -o stubify.exe stubify.c

  - Run this debugging version of stubify.exe under GDB, like this:

	    gdb stubify.exe
	    break rename
	    run foo

    where `foo' is the name of the program you tried to link when you
    saw the original error message which started this thread.

    PLEASE NOTE: `foo' must be a raw COFF image, not a .exe program!
    It should be a file without an extension, and you should be able
    to find it in the directory where you were linking that program.

    I suggest to copy `foo' into the same directory where you have the
    debugging version of stubify.exe with stubify.c and all the other
    source files, and run GDB from there.

  - Once stubify.exe stops at entry to `rename', you can single-step
    it by typing "next" (or "n" for short), and see what source line
    causes the problem.  You can examine variables with a command like
    this:
		print varname

    where "varname" is the name of a variable (acually, it can be any
    valid C expression that includes variable names, operators, and
    even function calls).

    To step into a function call, use "step" instead of "next".

Good luck, and thanks for working on this!
