Trouble with setting up a new compiler

[Blocks++Code]

I wanted to set up Code::Blocks for the ELF GCC on Windows.
I wanted to manage the code for my very little operating system kernel.

But there were some trouble with the configuration.
I had copied the GCC compiler settings and I had changed some settings.
Then the compiling and the linking have worked.

Today I started Code::Blocks and there was shown up a big error window. ("Compiler auto-detection")
All relative compiler paths are displayed invalid.
Why doesn't relative paths work any more, when I have added a custom compiler?
Is it a bug?

My settings in "default.conf":

Version (OS, C::B, compiler), platform, please?!

[Blocks++Code]

I use a nightly. So far as I know it is svn 8500.
But i have tried the latest. There is the same problem.

I work on a pc with Windows Vista.
The problem doesn't come from the compiler because I have copied the "user_sets" compiler settings to a predefined compiler stub and the error disappeared. (There were many other problems logically)

The compilers which I would add are an elf gcc (4.4.0) and nasm (2.0.7)

Then I have also tried to use absolute paths.
I have found, however, that it refuses anyway.

You are not supposed to change the config like that and what you did cannot work. If you do, bad things including crashes can happen. Only C::B itself shall read/write the config. If you want to "fiddle" with the compiler options, try the xml_compiler branch.

[Blocks++Code]

I configured Code::Blocks itself without change something in the config directly.
Because it was not working, I searched myself for the error in the file.

I would happy already if I could add a new compiler on the provided way.
Nevertheless, the xml_compiler branch sounds interesting.
