Despite consultation of the FAQ where the installation of multiple
versions of gcc alongside each other is discussed, I keep running into
this problem with recent gcj snapshots:

On a fresh RH8 installation, just with RH8 distribution's gcc3.2
appointed, after building gcc with the options:
--prefix=/usr/local/gcc/3.3/20030331 --enable-languages=c,c++,java
--enable-threads=posix. The LD_LIBRARY_PATH & LD_RUN_PATH env vars are
not set. 

When I try to link my application, this time with the snapshot gcc
version upfront on my PATH, with LD_LIBRARY_PATH pointing to the
snapshot's lib directory, ld reports:
/usr/local/gcc/3.3/20030331/lib/gcc-lib/i686-pc-linux-gnu/3.3/../../../ undefined reference to `_Unwind_FindEnclosingFunction@GCC_3.3'.

Sofar, the only way I have been able to link my app successfully, is to
install the snapshot to /usr using --prefix=/usr, obviously a recipe for

It seems that, no matter what, keeps referring to an old
version of, regardless the configuration options of the gcc
build, regarding the value of PATH and LD_LIBRARY_PATH environment
variables. Forcing the situation with symlinks does not seem to help.

Any help would be greatly appreciated.
