Too many words have been spent for nothing - I mean both bug reports of mine.

So, I have a practical question to which I can fins an answer myself, or to
which I can get the answer is shorter than the all the words already said in
vain, and the question is:

what mechanism WRT file paths is used to load, where necessary, libgcc_s.so.1:

1) absolute path related to system locations, like /lib, /usr/lib, etc.;
2) no path at all, but rather contents of LD_LIBRARY_PATH or another environment
variable ?
3) a path calculated according to 'gcc'  directory tree, e.g. 'gcc' is

/mnt/sdb8/sergei/AFSWD_debug/install/gcc-4.3.3/bin/gcc

, so its bin directory is simply

dirname(/mnt/sdb8/sergei/AFSWD_debug/install/gcc-4.3.3/bin/gcc) , i.e.

/mnt/sdb8/sergei/AFSWD_debug/install/gcc-4.3.3/bin

and, consequently, the 'lib directory is

/mnt/sdb8/sergei/AFSWD_debug/install/gcc-4.3.3/bin/../lib ==
/mnt/sdb8/sergei/AFSWD_debug/install/gcc-4.3.3/lib

?

I can answer the answer myself because I know about LD_DEBUG environment
variable and I have already tried it, though not yet in the places I need to
nail down this issue, but it will take more time from me than from those whi
know the answer "by construction".

Thanks in advance.
