Hi ! I found a workaround for this by removing the -fPIC Compiler option from devtools/bin/toolvars.pl. But i don't know if this is a good idea but it makes the build possible. But i still would like to have some asm expert tell me why gcc thinks that the ebx - register is destroyed even if it pushed before the operation and poped afterwards.
