But that does not happen. gcc often can't find it's libraries, which is why 
there are so many reports of "cannot compute suffix of object files".

I would like to be able configure gcc such that it goes into a directory of my 
choosing, and can find its libraries, without resorting to setting LD_LIBRARY_PATH.

I'm not interested in moving the gcc binary without moving the gcc libraries. 
That would not be so useful.

When I use the Sun compiler, it installs in /opt/sunstudio12.1. I never have to 
concern myself about the libraries - they are just found automatically. but 
/opt/sunstudio12.1 is not added to the linker search path.

Here's my linker search path:

drkirkby@hawk:~$ crle

Default configuration file (/var/ld/ld.config) not found
   Platform:	32-bit LSB 80386
   Default Library Path (ELF):	/lib:/usr/lib  (system default)
   Trusted Directories (ELF):	/lib/secure:/usr/lib/secure  (system default)
drkirkby@hawk:~$

But gcc is a lot more messing around.
