Greetings, I'm using pkgsrc on Solaris 9 to compile a C compiler from 
/usr/pkgsrc/lang/gcc3-c The problem is pkgsrc builds a compiler which 
does not support -m64 flag. Looking at Makefiles in pkgsrc I noticed 
that it passes --host=sparc-sun-solaris2 when configuring gcc, I think 
to build a compiler with 64-bit support it needs to be passed 
--host=sparcv9-sun-solaris2.9

Any ideas how I could tell pkgsrc to build a biarch (32/64 bit) C compiler?

Thanks
