from:
SUSE 9.1 running a 2.6.x kernel, so the first fix is kernel
2.6 related. When kernel shift from 2.4 to 2.6, the
/proc/self/maps is changed slightly. This make
VMem_FindUnmappedRegion thought the memory region beyond
0xc0000000 is also usable. But in fact, mostly, our TASK_SIZE is
configured to 0xc0000000. So I assume all address above
0xbfff0000 is not available to user space. And also, I assume
/proc/self/maps is always readable for the process itself, so
assert is not need at all. Based the two assumptions above, I
patched ilink and ilink.so like this:

Second. I found injected_execve is not need for SUSE 9.1. If
you want to use IDE integrated debugger, you have to remove
init_ExecveRedirect() in __libc_csu_init() first, then recompile
_initfini32.cpp, then ar it into libborcrtl.a and
libborcrtl_noshare.a. I dont know why yet, but I think that
mention it in the README file will be a great helpful.

I've test these two fixed for several hours, and BCB runs
quite stable for me.

If you have any further questions, pls mail

----------------------------------
配合以前做的补丁解决Kylix3-BCB在MandrakeLinux9.1和RedHat9.0等新版Linux不能编译的补丁
就可以在最新的Linux发行版(Mandrake10/FC1/FC2)下用Kylix3-BCB进行编程开发工作了，COOL
