It would be good if a patch similar to yours will work, so alloing gcc to be
installed in an arbitrary location and used without setting LD_LIBRARY_PATH. 

The fact is, a lot of people using Solaris do not have root access, so using
crle is not an option. 

It should be noted, gcc binaries from Blastwave install in a non standard
location (/opt/csw) and do run without the user having to set LD_LIBRARY_PATH.
Of course, you need root acces to install them, but they do *not* modify the
linker search path with crle, but work without doing that. 

Despite asking a couple of times, I've never managed to get an answer how the
Blastwave binaries achieve this. 

I'd like a pound (I'm English) for every time I have seen this issue raised on
Solaris forums. It is something wanted by many, but I believe the gcc
developers do not feel is necessary. 

Some have told be /usr/local is "a standard" though it's not a "standard"
reconised by any official body, like ISO, IEEE etc. But normal users cant write
there either.

PS, you could always ask your uni system admins if they would set you up in a
Solaris 10 zone. The memory overhead of a zone is quite small (well under 100
MB) and if in a zone, they could give you root access.
