Fixed. This was a kernel bug when trying to delete '' (rm -f ltdl.o '' 
). It returned EISDIR rather then ENOENT

No, not at all

No. You can think of SkyOS as  a unix system when it comes to the 
filesystem layout and available tools. A *nix emulation layer inside the 
kernel emulates a *nix environment by providing the well known *nix 
filesystem layout (/bin, /usr/, /etc, .....) as well as linking all 
available GNU tools into this locations. Same for the environment 
variables. The only real difference is the executable file format which 
is PE in SkyOS.
Note: If there is anything missing, like an environment variable, 
essential directory, gcc configuration, ... then I can easily fix this 
and make it available in the next distribution.

The runtime linker looks in following folders is this order:
- /boot/sytem/dll (primary location for DLLs)
- /lib
- /usr/lib
- /usr/local/lib
- LD_LIBRARY_PATH

Attached.

I'm going through every variable currently. I already found 
sys_lib_search_path_spec and sys_lib_dlsearch_path_spec which are not 
set correctly.

Thanks,
Robert!
