Building SPARC32PLUS

[Jim Watson <jim@amarooas.com.au>]

Hi,

I am building some applications (openoffice.org) using gcc and g++
jim@sun:~/vanilla$ gcc --version
gcc (GCC) 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)

jim@sun:~/vanilla$ g++ --version
g++ (GCC) 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)

When running the "file" command I have noticed the object files are 
SPARC e.g.
$ file something.o   blah ... SPARC

$ file everything.so  blah -... SPARC32PLUS

I assume the shared libs are different because they are linked to 
SPARC32PLUS files in /usr/lib...
is that right?

Also I notice that gcc -mcpu=v9 is needed to get object files like 
SPARC32PLUS.
Is that the correct behaviour?
I suppose I am wondering why gcc doesn't produce SPARC32PLUS by default.

thanks
jim
